Problem

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

Column I	Column II
(A) The dimensions of the rectangle of perimeter 36 cm, which sweeps out the largest volume when revolved about one of its sides, are	(p) 6
(B) Let $A(-1, 2)$ and $B(2, 3)$ be two fixed points, a point $P$ lying on $y = x$ such that perimeter of $\triangle PAB$ is minimum, then sum of the abscissa and ordinate of point $P$ , is	(q) 12
(C) If $x_1$ and $x_2$ are abscissae of two points on the curve $f(x) = x - x^2$ in the interval $[0, 1]$ , then maximum value of expression $(x_1 + x_2) - (x_1^2 + x_2^2)$ is	(r) 4
(D) The number of non-zero integral values of $a$ for which the function $f(x) = x^4 + ax^3 + \frac{3x^2}{2} + 1$ is concave upward along the entire real line is	(s) $\frac{1}{2}$
