A. the maximum pressure is exerted when the length and breadth form the base
B. the maximum pressure is exerted when length and height form the base
C. the maximum pressure is exerted when breadth and height form the base
D. the minimum pressure is exerted when length and height form the base

C. the maximum pressure is exerted when breadth and height form the base
Explanation:
Given length = 50 cm, breadth = 25 cm, and height = 10 cm of a wooden block.
We can calculate pressure using the formula, pressure = force / area.
In this case, we find that Pressure is inversely proportional to area. So the smaller the base area on the floor, the greater will be the pressure exerted by the wooden block.
- The least base area of the given block will be breadth * height = 25 * 10 = 250 sq.cm. = Maximum pressure.
- The maximum base area of the given block will be length * breadth = 50 * 25 = 1250 sq.cm. = Least pressure.
Option C is the answer.
