Answer: 12, 12, and 23

Step-by-step explanation:

By definition, when three lengths form a triangle, the sum of two of them must be greater that the third lenght.

To find out which of the options given in the problem form a triangle, you must add the first two lenghts and verify that the sum is greater than the third lenght.

Keeping this on mind, when you verify the last option you have:

12+12=24

24>23

Therefore, the answer is the last option.
