Problem

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

Column I	Column II
(A) $\lim_{x \to \frac{\pi^+}{2}} \tan^{-1}(\tan x)$	(p) 0
(B) $\lim_{n \to \infty} \left[ \sum_{r=1}^{n} \frac{1}{2^r} \right]$ ([·] denotes the greatest integer function)	(q) Doesn't exist
(C) $\lim_{x \to \infty} \sec^{-1} \left( \frac{x}{x+1} \right)$	(r) $-\frac{\pi}{2}$
(D) $\lim_{x \to \frac{\pi}{2}^-} \frac{\cos x}{(1 - \sin x)^{2/3}}$	(s) $\frac{\pi}{2}$
