First of all neither a even number can be prime, so then it's one that has a 3 in the ones place or 7 in that place. So it's none but the closest will be 70/79

C) The pair 70 & 79 is relatively prime.

What is Relatively prime ?

If the common factor between two numbers is only 1, then we can say that they are relatively prime or coprime numbers.

Therefore if the HCF of two numbers is 1 then they are said to be relatively primes.

Which one pair is relatively prime ?

Verifying Option A,

The HCF of 18 & 105 = 3

So, this pair is not relatively prime.

Verifying Option B,

The HCF of 35 & 110 = 5

So, this pair is not relatively prime.

Verifying Option C,

The HCF of 70 & 79 = 1

So, this pair is not relatively prime.

Verifying Option D,

The HCF of 94 & 98 = 2

So, this pair is not relatively prime.

Hence 70 & 79 are relatively prime.
