ο β. 3, 5, 7
ο c. 3, 5, 9
ο d. 2, 4, 8

B would be the answer.

Remember the triangle inequality theorem. The first two small numbers must be greater than the greatest number (15,13,30). These numbers in this example do make a triangle since the first two numbers (15, 13) are greater than the larger number, 30.
