The answer is A. 101.

The number series is a sequence of squares of numbers, starting with 16, which is the square of 4. The next number in the series is 196, which is the square of 14. The next number in the series is 144, which is the square of 12. The next number in the series is 121, which is the square of 11. The next number in the series should be 100, which is the square of 10. However, the number in the series is 101, which is not a square of any number. Therefore, 101 is the wrong term in the series.
