In how many ways can the letters of DAUGHTER be arranged so that the vowels come together?
- A 720
- B 40,320
- C 2,160
- D 4,320 Correct
Correct Answer: Option D
Vowels A, U, E as one block + D, G, H, T, R → 6 units: 6! = 720
Vowels inside the block: 3! = 6
720 × 6 = 4,320
Trap: 720 forgets to arrange the vowels.
Answer: 4,320
