Answer:
Option A is correct

Step-by-step explanation:
Volume of cylinder(V) is given by:

where,
r is the radius of the cylinder and h is the height of the cylinder respectively.
As per the statement:
Radius of the cylinder(r) = 12 unit and height of the cylinder(h) = 7 units
Substitute the given values in [1] we have;

⇒
cubic units.
Therefore, the volume of the cylinder is,
