The best option to enable the capability of an organization to sustain the delivery of products and services within acceptable time frames and at predefined capacity during a disruption is B. Business continuity plan (BCP). This is because a BCP is a documented collection of procedures and information that guides the organization to prepare for, respond to, and recover from a disruption, such as a natural disaster, a cyberattack, or a pandemic. A BCP aims to ensure the continuity of the critical business functions and processes that support the delivery of products and services to the customers and stakeholders. A BCP also defines the roles, responsibilities, resources, and actions required to maintain the operational resilience of the organization in the face of a disruption.

Chain of custody forms with points of contact are the best way to enable an organization to maintain legally admissible evidence because they document the sequence of control, transfer, and analysis of the evidence, and every person who handled it, the dates and times, and the purpose for each action1. They also ensure the authenticity and integrity of the evidence, and prevent tampering or loss1. Documented processes around forensic records retention are not sufficient to maintain legally admissible evidence because they do not track or verify the handling of the evidence. Robust legal framework with notes of legal actions are not sufficient to maintain legally admissible evidence because they do not record or validate the preservation of the evidence. Forensic personnel training that includes technical actions are not sufficient to maintain legally admissible evidence because they do not account or certify the custody of the evidence.

Confidentiality is the security objective that best ensures that information is protected against unauthorized disclosure. Confidentiality means that only authorized parties can access or view sensitive or classified information. Integrity means that information is accurate and consistent and has not been tampered with or modified by unauthorized parties. Authenticity means that information is genuine and trustworthy and has not been forged or misrepresented by unauthorized parties. Nonrepudiation means that information can be verified and proven to be sent or received by a specific party without any possibility of denial. References:

A culture that supports security encourages behaviors that protect information assets.
"Organizational culture has a significant impact on how employees approach security, influencing their behavior and adherence to policies."

Information asset classification is the process of identifying, labeling, and categorizing information assets based on their value, sensitivity, and criticality to the organization. Information asset classification helps to establish appropriate security controls, policies, and procedures for protecting the information assets from unauthorized access, use, disclosure, modification, or destruction. One of the key elements of information asset classification is assigning owners to each information asset. Owners are responsible for managing the information asset throughout its lifecycle, including defining its security requirements, implementing security controls, monitoring its usage and performance, reporting any incidents or breaches, and ensuring compliance with legal and regulatory obligations. Therefore, assigning responsibility to the database administrator (DBA) is the best way to address the situation where several production databases do not have owners assigned to them.
