remember, for any right triangle, the hypotonuse is always longer than the 2 legs

if the legs are length a and b and the hypotnuse is c then
a²+b²=c²

test each

7²+24²=25²?, 49+576=625? yes, this works
12²+15²=20?, 144+225=400?, no
9²+11²=14?, 81+121=196? no
15²+18²=21²? 225+324=441? no

first one is answer, 7 24 25
