For three lengths two be able to be the sides of a triangle, the longest side must be less than the sum of the two other sides.

A.
25 is the longest side.
16+10=26
25<26

It is possible.

B.
15 is the longest side.
13+12=25
15<25

It is possible.

C.
18 is the longest side.
5+10=15
18 is NOT less than 15.

It is not possible.

D.
15 is the longest side.
8+8=16
15<16

It is possible.

Therefore, the answer is c.

Hope this helps!
