Answer»

We know that, 

According to the Pythagorean triplet, 

For a natural number m, 

(2m, m2 – 1, m2 + 1) is a Pythagorean triplet. 

Hence, 

Considering the Pythagorean triplet, 

Let m = 4 

2m = 8 

m2 – 1 = 15 

m2+ 1 = 17 

Thus, 

(8, 15, 17) is the Pythagorean triplet. 

Hence, 

Option (D) is the correct option.
