Answer: (3) 45 degree

Explanation:-
For answer look in below diagram according to question, 

RE: The angle of elevation of the Sun when the length of the shadow of a pole is equal to its height is :


tan A = BC/AB
tan A = H/H
     = 1
tan A = tan 45
A = 45 degree.

Then, the value of the elevation of the sun when  the length of the shadow of a pole is equal to its height is 45 degree. 

Hence, the correct answer is option (3) 45 degree.
