Answer:

The correct option is B.

Explanation:

It is given that the circumference of a circle is 7π units.

The circumference of the circle is

$S=2\pi r$

$7\pi =2\pi r$

7=2r

r=3.5

The area of the circle is

$A=\pi r^2$

$A=\pi (3.5)^2$

$A=12.25\pi$

The area of circle is 12.25π square unit.

Therefore the correct option is B.
