Explanation:

Let's solve:

- Original number: 7 8 5 4 6 9 3 2

- Arranged in descending order: 9 8 7 6 5 4 3 2

- Compare each position:

- 1st digit: 7 ? 9 (no)

- 2nd digit: 8 ? 8 (yes)

- 3rd digit: 5 ? 7 (no)

- 4th digit: 4 ? 6 (no)

- 5th digit: 6 ? 5 (no)

- 6th digit: 9 ? 4 (no)

- 7th digit: 3 ? 3 (yes)

- 8th digit: 2 ? 2 (yes)

- So, three digits (positions 2, 7, 8) remain in the same place.

Relevant options:

- Option 1: None (not correct)

- Option 2: Three ( Correct)

- Option 3: One (not correct)
