The correct answer is D

Explanation

By the Triangle Inequality, the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. Therefore,??+??greater than?, or 2 +??greater than 12. Thus,??greater than 10, which eliminates options (A), (B), and (C). Also by the Triangle Inequality,??+??greater than?, or 14 greater than?, which eliminates choice (E). Therefore, of the given choices, only choice (D), 12, could be the length of side.
