Solution:

(d) (8, 15, 17

Explanation:

According to the property of a perfect square,

we have for every number m>1, we have (2m, m2-1, m2+1) as a Pythagorean triplet

Using the above condition we can write as

2m=8

m=8/2=4

Then m2=16

m2 – 1 = 16 – 1 = 15

m2 + 1 = 16 + 1 =17

Therefore the Pythagorean triplet is = (2m, m2-1, m2+1) = (8, 15, 17)
