An antenna is fed with $$200 \pi W$$ power. The efficiency of the antenna is 75%. If the radiation pattern of the antenna is
$$P(\theta, \phi) = \sin^2 \theta \times \sin^2 \phi$$ for $$0 \leq \phi \leq \pi$$ (elevation angle).
= 0 elsewhere
Find the radiation intensity in the direction of maximum radiation

A

225 W/steradian

B

150 $$\pi$$ W/steradian

C

200 $$\pi$$ W/steradian

D

250 W/steradian
