Explanation:
Sensitive data exposure occurs when information is not properly secured through encryption and secure transport mechanisms; it can quickly become an easy and broad method for attackers to compromise information. Web applications must enforce strong encryption and security controls on the application side, but secure methods of communications with browsers or other clients used to access the information are also required. Security misconfiguration occurs when applications and systems are not properly configured for security, often a result of misapplied or inadequate baselines. Insecure direct object references occur when code references aspects of the infrastructure, especially internal or private systems, and an attacker can use that knowledge to glean more information about the infrastructure. Unvalidated redirects and forwards occur when an application has functions to forward users to other sites, and these functions are not properly secured to validate the data and redirect requests, thus allowing spoofing for malware or phishing attacks.

Patents protect processes (as well as inventions, new plantlife, and decorative patterns). The other answers listed are answers to other questions.

Explanation
Whereas a contract spells out general terms and costs for services, the SLA is where the real meat of the business relationship and concrete requirements come into play. The SLA spells out in clear terms the minimum requirements for uptime, availability, processes, customer service and support, security controls and requirements, auditing and reporting, and potentially many other areas that define the business relationship and the success of it.

All the others are valid methods of data discovery; user-based is a red herring with no meaning.
