मान लीजिए $A = \{ \theta : 2\cos^2 \theta + \sin \theta \le 2 \}$ और $B = \{ \theta : \frac{\pi}{2} \le \theta \le \frac{3\pi}{2} \}$,तो $A \cap B$ है

• A
  $\left\{ \theta : \theta \in \left[ \pi, \frac{3\pi}{2} \right] \right\}$
• B
  $\left\{ \theta : \theta \in \left[ \frac{\pi}{2}, \frac{7\pi}{6} \right] \right\}$
• C
  $\left\{ \theta : \theta \in \left[ \frac{\pi}{2}, \frac{\pi}{6} \right] \right\}$
• D
  $\left\{ \theta : \theta \in \left[ \frac{\pi}{2}, \frac{5\pi}{6} \right] \cup \left[ \pi, \frac{3\pi}{2} \right] \right\}$
