3 2 4 9 1 8 7 6 3 2 1 5 6 4 7 8 3 9 4 6 5 7 4 1 5 7 2
Condition to be checked:
Even digit, immediately preceded by a perfect square, and immediately followed by an odd digit.
Perfect Square → Even Digit → Odd Digit
Let's analyze the series for this pattern:
3 2 4 9 1 8 7 6 3 2 1 5 6 4 7 8 3 9 4 6 5 7 4 1 5 7 2
Thus, two such even digits are immediately preceded by a perfect square and immediately followed by an odd digit.
Hence, the correct answer is "Option 2".
