Step-by-step explanation:
Option B:
is the area of the compact disc.
Explanation:
The diameter of the compact disc is
.
To determine the area of the compact disc, let us substitute the values in the area of the circle formula,
where 
Substituting the value of d in
, we get,

Thus,
and
. Let us substitute these values in
, we get,

Simplifying, we have,

Multiplying, we get,

Thus, the area of the compact disc is 
Hence, Option B is the correct answer.
