Correct Answer: 1


Solution : The highest common factor (HCF) of any set of prime numbers is always 1.
This is because prime numbers are numbers that have only two distinct positive divisors i.e. 1 and the number itself.
Since A, B, and C are distinct prime numbers, they do not have any common factor instead of 1.
Hence, the correct answer is 1.
