$ \begin{aligned} & 	ext { If } x \in\left(0, \frac{\pi}{4}ight) \ & \quad \cot x>	an x \ & 	herefore \operatorname{In} \sin x<0 	ext { in } x \in\left(0, \frac{\pi}{4}ight) \ & \Rightarrow \quad x \in\left(0, \frac{\pi}{2}ight) \Rightarrow \operatorname{In}(\operatorname{cosec} x)>0 \ & \Rightarrow 5^{	ext {In } \operatorname{cosec} x}>4^{	ext {In } \operatorname{cosec} x} 	ext { similarly } C \& D \end{aligned} $
