B Correct answer
Explanation

After cutting 2 cm squares from each corner, the new dimensions are: length = 25 - 2 - 2 = 21 cm, width = 20 - 2 - 2 = 16 cm, and height = 2 cm (the flaps). Volume = length × width × height = 21 × 16 × 2 = 672 cm³. This is a classic optimization/application problem where cutting and folding creates an open box.
