Correct Answer: 2

Solution : Given $ heta$ is an acute angle
Also, $ an heta+\cot heta=2$
$\frac{\sin heta}{\cos heta}+\frac{\cos heta}{\sin heta} = 2$
⇒ $\frac{\sin^2 heta + \cos^2 heta}{\sin heta \cos heta} = 2$
⇒ $1 = 2\sin heta \cos heta$
⇒ $\sin2 heta = 1$
⇒ $2 heta = 90°$
⇒ $ heta = 45°$
Now, $ an ^{200} heta+\cot ^{200} heta$
$= ( an 45°)^{200} + (\cot 45°)^{200} = 1^{200} + 1^{200} = 2$
Hence, the correct answer is 2.
