I believe the answer to this one is 18.
there are double letters in both so we can write them in form ABB. Which has 3 forms.
We can also put either vowels or consonants first (2 more combinations)
Thus we have
2*3*3 = 18
So B.

Separating all vowels: AAI
Separating all consonants: MXM
These 2 groups can be arranged in 2! ways.
Each group can now be arranged in 3!2!3!2! ways
So total number of ways is 2!∗3!2!∗3!2!2!∗3!2!∗3!2!
= 18
option: B
