You're hiding the list of choices, and you don't say "prime factor of" WHAT, so there's really nothing to work with here.
To identify a prime factor, first understand that it must be a prime number itself. Find the factors of the given number, then check which of these are prime by ensuring they are only divisible by 1 and themselves. For example, the prime factors of 28 are 2 and 7.
