MNOR



A. 24

B. 8

C. 32

D. 4

Answer 1

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.

Answer 2

Factorial 4

Answer 3

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

Answer 4
