I think it's C) customExecutionStats. Feels tricky.

I’m pretty confident that executionStats and queryPlanner are valid, but I’m torn between customExecutionStats and allPlansExecution for the unsupported one.

I feel like customExecutionStats sounds familiar, but I can't recall if it's actually supported or not.

I remember practicing a question about verbosity modes, and I think allPlansExecution is the one that doesn't fit.

I think the explain() method supports executionStats and queryPlanner, but I'm not sure about customExecutionStats.
