Correct Answer - Option 1 : Three
Left 9, 6, 9, 5, 3, 5, 9, 5, 7, 3,7, 5, 9, 5, 1, 7, 6, 5, 3, 7, 9, 5, 6, 3, 7, 9, 8, 3, 7, 8 Right

9, 6, 9, 5, 3, 5, 9, 5, 7, 3,7, 5, 9, 5, 1, 7, 6, 5, 3, 7, 9, 5, 6, 3, 7, 9, 8, 3, 7, 8
There are three numbers i.e. (9, 5, 3), (9, 5, 1), and (9, 5, 6)
Hence, "Three" is the correct answer.
