C Correct answer
Explanation

Ratio A:B:C = 2:3:5. If A = 3 pounds, then 2 parts = 3, so 1 part = 1.5. C = 5 parts = 5 * 1.5 = 7.5 pounds.

AI explanation

The ratio of components A, B and C is 2:3:5, meaning A represents 2 parts and C represents 5 parts of the total mixture. Since 3 pounds corresponds to the 2 parts of A, one single part equals 1.5 pounds. The quantity of C is 5 parts, so multiplying 5 by 1.5 gives 7.5 pounds.
