B Correct answer
Explanation

Class 3 spelunkers have no cave restrictions, but rule 6 limits exploration of Benny, Caesar, Ewell, Fields, Hope to 2 caves maximum. Since they've already explored Benny, they can add Caesar (rule 4 satisfied), leaving 1 more from that set. They can freely explore Abbott, Dangerfield, Guinness from outside the restricted set. Total maximum: 2 from restricted set + 3 unrestricted = 5 caves.
