Correct answer
3
Why this answer is correct
Given: (Left) 5 3 8 5 7 4 3 7 4 (Right)
Now,
We need to identify odd numbers that are immediately preceded by an odd number and immediately followed by an even number.
So, the required condition is: Odd Number – Odd Number – Even Number
(Left) 5 3 8 5 7 4 3 7 4 (Right)
Total odd numbers satisfying the condition = 3
Hence, the correct answer is "Option 1".
