D. Deploy the feature to a subset of users, and gradually roll out to all users if there are no errors reported. Explanation: Since the error budget is exhausted, normal practice is to freeze production deployments to protect reliability. However, there is an urgent customer need for this new feature, so a controlled, gradual rollout (e.g., canary or phased deployment) is the safest way to proceed. This approach: Limits risk by exposing only a subset of users to the new release. Allows monitoring for new errors or performance issues during rollout. Enables quick rollback if issues are detected, minimizing impact on overall user base. This aligns with SRE principles balancing risk management and business needs.

D - it's a business critical release. SRE best practices allow for exceptions to deployment freezes with risk mitigation. In this scenario a gradual rollout is the best course of action.
