Answer 1

Answer: (B), (C)

The correct options are
B

8,15,16

C

20,21,29

For any natural numbers to be a Pythagorean triplet, the sum of squares of two numbers should be equal to the square of the third number.

Here,

$8^2$ + ${15}^2$ = ${17}^2$.

${20}^2$ + ${21}^2$ = ${29}^2$.

Here, the sum of the squares of two numbers equals the square of the third number and thus they form a Pythagorean triplet.
