Answer & Solution

Correct Answer

(C) \(\frac{1}{3}\)

Step-by-step Solution

Detailed explanation

\(\begin{aligned} & \int_0^{\frac{\pi}{4}}\left(\tan ^2 x+\tan ^4 x\right) d x \\ & \int_0^{\frac{\pi}{4}}\left(1+\tan ^2 x\right) \tan ^2 x d x \\ & \int_0^{\frac{\pi}{4}} \sec ^2 x \cdot \tan ^2 x d x \\ & \text {Put, } \tan x=t \\ & \sec ^2 x d x=d t \end{aligned}\) when…
