Answer:

C. 5, 9, 12

Explanation:

There is a rule in the triangle that if you add any 2 sides measure of the triangle, it must be bigger than the measure of the 3rd side.

Let's Check

A. 19, 6, 13

19 + 6 > 13

6 + 13 = 19

19 + 13 > 6

This is not meet the rule, so this option is wrong.

B. 10, 1, 8

10 + 1 > 8

1 + 8 < 10

This is not meet the rule, so this option is wrong.

C. 5, 9, 12

5 + 9 > 12

9 + 12 > 5

5 + 12 > 9

This meets the rule, so this option is correct.
