(D) The period of $\sin(a	heta)$ is $\frac{2\pi}{|a|}$ and the period of $\cos(b	heta)$ is $\frac{2\pi}{|b|}$.For $f(	heta) = \sin \frac{	heta}{3} + \cos \frac{	heta}{2}$, the period of $\sin \frac{	heta}{3}$ is $T_1 = \frac{2\pi}{1/3} = 6\pi$.The period of $\cos \frac{	heta}{2}$ is $T_2 = \frac{2\pi}{1/2} = 4\pi$.The period of the sum of two periodic functions is the Least Common Multiple $(LCM)$ of their individual periods.We need to find the $LCM(6\pi, 4\pi)$.$LCM(6, 4) = 12$.Therefore, the period of $f(	heta)$ is $12\pi$.

The period of the function $f(\theta) = \sin \frac{\theta}{3} + \cos \frac{\theta}{2}$ is (in $\pi$)
