Solution

The correct option is A Statement I alone is sufficient to answer the problem.
The triangle formed by joining the heads of the shadow and the actuaal person will be similar in both the cases due to sun's position.
Beacuse of I, we can use the fact that the sides of both the triangles will be in the same ratio and thus find the height Pramod.
