Solution

The correct option is B 1

The Highest Common Factor (HCF) of two or more given numbers is the highest (or greatest) of their common factors.
It is also known as Greatest Common Divisor (GCD).

7 and 9 are prime numbers.
So, factors of 7 are 1 and 7 and
factors of 9 are 1 and 9.

1 is the only common factor of 7 and 9.

Hence, 1 is the highest common factor (HCF) of 7 and 9.
