Explanation:

The given number series is: 27, 81, 1331, 125a.

To identify the wrong number in the series, we need to find the pattern or rule that governs the series.

Pattern:
Let's analyze the given number series step by step:

- The first number in the series is 27.
- The second number is obtained by multiplying the previous number by 3 (27 * 3 = 81).
- The third number is obtained by multiplying the previous number by 11 (81 * 11 = 891).
- The fourth number is obtained by multiplying the previous number by 125 (891 * 125 = 111375).

Analysing the Wrong Number:
Now, let's analyze the last number in the series, which is 125a.

- The previous number in the series is 111375.
- If we multiply 111375 by 125, we should get the next number in the series.
- However, the given number is represented as 125a, which indicates that 'a' is a variable and can take any value.

Conclusion:
Since the series follows a clear pattern of multiplying each number by a specific factor, the inclusion of a variable 'a' in the last number breaks the pattern. Therefore, the wrong number in the series is 125a, which is option D.
