मान लीजिए $A = \{\theta \in R : (\frac{1}{3} \sin \theta + \frac{2}{3} \cos \theta)^2 = \frac{1}{3} \sin^2 \theta + \frac{2}{3} \cos^2 \theta\}$. तो:

  • A
    $A \cap [0, \pi]$ एक रिक्त समुच्चय है
  • B
    $A \cap [0, \pi]$ में केवल एक बिंदु है
  • C
    $A \cap [0, \pi]$ में केवल दो बिंदु हैं
  • D
    $A \cap [0, \pi]$ में दो से अधिक बिंदु हैं
