Problem

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

Column I		Column II
(A) Number of the values of $x$ lying in $\left(0, \frac{\pi}{2}\right)$ at which $f(x) = \ln(\sin x)$ is not monotonic, is	(p)	0
(B) If the greatest interval of decrease of the function $f(x) = x^3 - 3x + 2$ is $[a, b]$ , then $a + b$ equals	(q)	2
(C) Let $f(x) = \frac{x^2 + 2}{[x]}$ , $1 \le x \le 3$ where $[. ]$ greatest integer function, then least value of $f(x)$ is	(r)	-3
(D) Set of all possible values of $a$ such that $f(x) = e^{2x} - (a+1)e^x + 2x$ is MI for all $x \in R$ is $(-\infty, a]$ , then $a$ equals	(s)	3
