    I think it's A, however, you'll want someone to confirm that for you. This is because it would be 4!, therefore 4 x 3 x 2 x 1, which is 24, and since there are no repeated letters, nothing needs to be divided.

    Yup, @brinazarski is correct. It's 4!, no repeated letters and any permutation is valid.
