Correct option is C)

Circumference of cylinder is $C=2πr$

It is given that the circumference of water tank is $264$ cm, therefore,

$C=2πr⇒264=2πr⇒r=2π264 =π132 $

Here, the radius is $π132 $ cm and height is $12$ cm.

Thus,

$A=2πrh=2π×π132 ×12=2×132×12=3168$ cm$_{2}$

Hence, the curved surface area of cylindrical water tank is $3168$ cm$_{2}$.
