B Correct answer
Explanation

Working backwards: If he ends with 0 flowers after temple 3, and each pond visit doubles the flowers, let x be initial. After doubling: 2x, 2(2x-x), 2(2(2x-x)-x) = 0. Solving: x = 7. Or working backwards: 0 → 3.5 (before 3rd pond doubling) → 7 flowers before temple 3 offering. The minimum integer solution is 7.
