Is there any similar themed advice for managing same-seniority coworkers handballing their responsibilities?

Person A owns task

Person A: I don't know much about task, but person B seems like an expert. Person B, please take over task

Person B is no more or less qualified at task than person A

Perhaps you shouldn't allow handover of such responsibility or tasks. Force Person A to own task but allow Person B to assist Person A. Surely Person A won't mind help Frontera on B.

Person B should probably accept but present the trade off. Allow the manager to decide what matters. Confidently state what options are possible within timeframe X

Person A may legitimately view person B as more qualified. Whether or not this is true.
