Alright. Let's start with Circumference.

The formula for that is 2piR.

Radius of circle is half of diameter. 14/2=7

Plug it in, 2*pi*7

Simplify, answer is 14 pi

Area, formula is pi(R*R) (Sorry can't do squared)

Taking from before, pi*49

Simplify, it's 49 pi

Total: it's C=14 pi, A= 49 pi, or choice A

Hope this helped!
