Eshan purchased a new building for her business. Being in the prime location, she decided to make some more money by putting up an advertisement sign for a rental ad income on the roof of the building.

From a point P on the ground level, the angle of elevation of the roof of the building is `30^@` and the angle of elevation of the top of the sign board is `45^@`. The point P is at a distance of 24 m from the base of the building.

If the point of observation P is moved 10 m towards the base of the building, then the angle of elevation `theta` of the roof of the building is given by

A

`tan theta = sqrt3`

B

`tan theta = 2/sqrt3`

C

`tan theta = 1/2`

D

`tan theta = 1`
