A team is choosing how to build a multi-step research agent. They want structured state management and are already invested in a graph-based orchestration style elsewhere in their stack. Which factor should drive the framework choice?

Answer: B — State management needs, control granularity, and fit with the team's existing stack and familiarity

The exam wants selection criteria, not brand loyalty to one framework. State needs, control granularity, ecosystem fit, and team familiarity are the actual decision factors — popularity and recency aren't.
