Answer: Replace the application's features with appropriate microservices in phases.
The correct approach is B. Replacing features with microservices in phases allows for incremental changes, minimizing disruption to the business. This phased approach (often using the Strangler Fig pattern) reduces risk compared to a full rewrite (C or D) and avoids the pitfalls of a big-bang deployment. Option A does not address architectural changes to microservices. Option C is risky due to the complexity of a single effort, and Option D delays benefits and incurs dual maintenance costs until replacement.
