Match the entries of the following two columns.

Column I	Column II
(A) The least value of the function $f(x) = 2 \cdot 3^{3x} - 3^{2x} \cdot 4 + 2 \cdot 3^x$ in $[-1, 1]$ is	(p) 5
(B) The minimum value of the polynomial $f(x) = (x-1)(x+1)$ is	(q) 1
(C) The value of the polynomial $\int_{1}^{3} (x-2)[-x] dx$ (where $[- \cdot]$ denotes the greatest integer function) is	(r) 3
(D) If period of the function $f(x) = \sin 36x \tan 42x$ is $p$ , then $\frac{18p}{\pi}$ equals	(s) 0
