Correct Answer

Explanation

One may opt for an approximation algorithm for the following reasons

1 pts

Some problems cannot be solved exactly
The algorithm to find the exact solution may be unacceptably slow because of the complexity of the problem
It may be a part of a more sophisticated algorithm that solves a problem exactly
