Answer:
The correct answer is D, 7 large buckets and 3 small buckets.
Explanation:
A wouldn't be the answer because 6 large buckets and 4 small buckets give you 10 buckets but 202 clams.
B wouldn't give you the answer because 8 large buckets and 2 small buckets give you 226 clams.
C isn't correct because 5 large buckets and 5 small buckets give you 190 clams.
D is correct, giving you 214 clams because 25 times 7 is 175 and 3 times 13 is 39. 175+39 is 214.
