Why are interval estimates needed in addition to point estimates?

A. The point estimate is just a random guess as to its counterpart, so a range of values is needed to give confidence.

B. The point estimate is guaranteed to be the same as its counterpart, so a range of values of estimates is excessive.

C. The point estimate is not guaranteed to be the same as its counterpart, so a range of values of estimates is needed.
