Answer:

66 in

Explanation:

the circumference can be calculated as:

$C=d\cdot\pi$

Where d is the diameter and π is 22/7.

So, replacing the values, we get:

$C=21\cdot\frac{22}{7}=\frac{21\cdot22}{7}=\frac{462}{7}=66\text{ in}$

Therefore, the circumference is 66 in.

With this information you should chose D regardless but that's also up to you I would though and E is correct.
