(C) Given equation: $3 \sec^2 	heta = 2 \operatorname{cosec} 	heta$ $\Rightarrow \frac{3}{\cos^2 	heta} = \frac{2}{\sin 	heta}$ $\Rightarrow \frac{3}{1 - \sin^2 	heta} = \frac{2}{\sin 	heta}$ $\Rightarrow 3 \sin 	heta = 2 - 2 \sin^2 	heta$ $\Rightarrow 2 \sin^2 	heta + 3 \sin 	heta - 2 = 0$ $\Rightarrow (2 \sin 	heta - 1)(\sin 	heta + 2) = 0$ Since $\sin 	heta$ cannot be $-2$,we have $\sin 	heta = \frac{1}{2} = \sin \frac{\pi}{6}$. The general solution for $\sin 	heta = \sin \alpha$ is $	heta = n \pi + (-1)^n \alpha$. Therefore,$	heta = n \pi + (-1)^n \frac{\pi}{6}, n \in Z$.
