Solution

The correct option is E None of these

There are 8 letters in the word 'SOFTWARE' including 3 vowels (O, A, E) and 5 consonants (S, F, T, W, R).
Considering three vowels as one letter, we have six letters which can be arranged in 6P6 = 6! ways.
But corresponding to each way of these arrangements, the vowels can be put together in 3! ways.
Number of arrangements = 6! × 3
=6×5×4×3×2×1×3×2×1
= 4320
