Verified By Collegedunia
The Correct Option is
B
Solution and Explanation
VOWEL has 5 letters. Vowels = O, E ⇒ keep them together as a block. Treat OE as one block → blocks = [OE, V, W, L] = 4 items ⇒ \( 4! \) ways. Within the block OE: 2! ways to arrange. \[ \text{Total} = 4! \cdot 2! = 24 . 2 = \boxed{48} \]
