C)
15
D)
Cannot be determined
E)
None of these

Answer: Option D

Explanation

$\begin{array}{l} Let the total number of sweets be x \\ According to the question, \\ \frac{x}{112 - 32} - \frac{x}{112} = 6 \\ \Rightarrow \frac{x}{80} - \frac{x}{112} = 6 \\ \Rightarrow \frac{7 x - 5 x}{560} = 6 \\ \Rightarrow \frac{2 x}{560} = 6 \\ \Rightarrow x = \frac{560 \times 6}{2} = 1680 \\ ∴ Required answer = \frac{1680}{112} = 15 \end{array}$

Hence, option D is correct.
