Solution

The correct option is B relatively prime or co-prime numbers
The numbers whose GCD is $1$ are called relatively prime or co-prime numbers.

For example, $15, 33$ and $22$ are relatively prime numbers.

Using prime factorization,
$15 = 3 \times 3$
$33 = 3 \times 11$
$22 = 2 \times 11$

They have no prime factors in common.
$∴$ GCD $= 1$ as $1$ is always a factor of all numbers.
