Answer: D) 9, 12, 15

Explanation:

The side lengths need to satisfy the Pythagorean theorem,
a^(2)+b^(2)=c^(2)

A)
2^(2)+3^(2)=4^(2) \longrightarrow 13=16, which is false.

B)
7^(2)+11^(2)=14^(2) \longrightarrow 170=196, which is false.

C)
8^(2)+10^(2)=12^(2) \longrightarrow 164=144, which is false.

D)
9^(2)+12^(2)=15^(2) \longrightarrow 225=225, which is true.
