Problem

Match the statement of Column I with values of Column II.

Column-I	Column-II
(A) The tangents of two acute angles are 3 and 2. The sine of twice their difference is	(p) 1
(B) If $n = \frac{\pi}{4\alpha}$ , then $\tan \alpha \tan 2\alpha \tan 3\alpha \dots \tan(2n-1)\alpha$ is equal to	(q) 0
(C) If $x = y \cos \frac{2\pi}{3} = z \cos \frac{4\pi}{3}$ , then $xy + yz + zx =$	(r) $\frac{1}{2}$
(D) The ratio of the greatest value of $2 - \cos x + \sin^2 x$ to its least value is	(s) $\frac{7}{25}$

(t)

\frac{13}{4}
