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.

The height of the building (with the sign board) is

A

`24 sqrt3`

B

`24 sqrt 2`

C

24 m

D

12m
