Statement-1 (Assertion) and Statement-2 (Reason) Each of these questions also has four alternative
\( \mathrm{P} \) choices, only one of which is the correct answer. You have to select the correct choice as given below.

(a) Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1
(b) Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1
(c) Statement1 is true, Statement-2 is false
(d) Statement-1 is false, Statement-2 is true
Statement-1 \( (\cos \theta+i \sin \theta)^{3}=\cos 3 \theta+i \sin 3 \theta \), \( i=\sqrt{-1} \)
Statement-2 \( \left(\cos \frac{\pi}{4}+i \sin \frac{\pi}{4}\right)^{2}=i \)
