(A) 24
(B) 36
(C) 144
(D) 720
Correct Option is: B
There are 3 consonants and 3 vowels in the word DILUTE.
Out of 6 places, 3 places odd and 3 places are even.
3 vowels can arranged in 3 even places in 3p3 ways = 3! = 6 ways.
And then 3 consonants can be arranged in the remaining 3 places in 3p3 ways = 3! = 6 ways.
Hence, the required number of ways = 6 x 6 = 36
