Answer:

Option B, $18.11 \frac{N}{cm^{2}}$

Explanation:

Given-

The average surface area of one foot pad of an elephant is $2920$ $cm^{2}\\$

Weight of an Asian elephant is $52900$ newton

As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.

Thus, pressure on one foot pad of elephant is $\frac{52900}{2920} \frac{N}{cm^{2}} \\$

$= 18.11\frac{N}{cm^{2}}$

Hence, option B is correct answer
