Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: The prompt is essentially asking for the maximum number of 5 x 5 squares that can be cut from a larger 15 by 15 square. Since each 'row' and each 'column' of the larger square can be sub-divided into 3 'pieces' each, we have (3)(3) = 9 total smaller squares (at maximum).
The question and answer:

Options:
(A) 5
(B) 10
(C) 16
