C Correct answer
Explanation

Rule 4 restricts Caesar exploration until Benny is completed - this applies since Caesar is in the selectable pool. Rule 5 restricts Fields until Ewell is completed, but since the spelunker has done Ewell, this doesn't actually constrain. Rule 6 always restricts selection to 2 from {Benny, Caesar, Ewell, Fields, Hope}. Therefore rules 4 and 6 are the active constraints.
