Option 2: Side lengths 6, 8, 10
This set of side lengths follows the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, 6 + 8 = 14, which is greater than 10, 6 + 10 = 16, which is greater than 8, and 8 + 10 = 18, which is greater than 6. Therefore, Option 2 will make a valid triangle.
