Understanding the enterprise's risk tolerance is the most important step for the CTO to create the appropriate risk policies for IT, as it would help to define the acceptable level of risk exposure and the risk appetite for mobile applications. Risk tolerance is the degree of uncertainty that an enterprise is willing to accept in pursuit of its objectives, and it reflects the enterprise's culture, strategy, and stakeholder expectations. Risk policies for IT should be aligned with the enterprise's risk tolerance, as well as its mission, vision, and goals. The other options are not as important, as they are more related to the implementation or measurement of risk management, rather than the establishment of risk policies.

Effective risk management in IT governance requires that risk evaluation is embedded in the management processes of the organization. This means that risk evaluation is not a separate or isolated activity, but rather an integral part of the planning, execution, monitoring, and reporting of IT activities and initiatives.
Embedding risk evaluation in the management processes can help:
* Identify and assess the potential threats and opportunities that may affect the achievement of IT and business objectives
* Align the IT risk appetite and tolerance with the enterprise risk appetite and tolerance
* Prioritize and allocate the resources and actions to address the risks based on their impact and likelihood
* Monitor and report the risk performance and outcomes in relation to the IT value drivers and benefits
* Embed the risk culture and awareness across the organization

Using the life cycle approach to govern information assets is the greatest benefit for an organization, because it helps to optimize the overall costs associated with the creation, storage, processing, distribution, and disposition of information. The life cycle approach involves managing information according to its value, utility, and risk throughout its lifespan1. By using the life cycle approach, an organization can ensure that it only collects, creates, and retains the information that is relevant, accurate, and useful for its business objectives and processes2. It can also ensure that it stores, protects, and disposes of the information in a cost-effective and secure manner, complying with the legal and regulatory requirements2. The life cycle approach also helps to improve the performance, availability, and accessibility of the information, as well as its quality and integrity3. By using the life cycle approach, an organization can reduce the operational costs, storage costs, compliance costs, and risk exposure costs associated with its information assets4. Therefore, using the life cycle approach to govern information assets is the greatest benefit for an organization.
