Explanation:

Female population = (Total population – Male population)

Therefore, the percentage increase in Female population in 1996, 1999, 2004 and 2005 is as given below:

1996: $\frac{330-300}{300}$ × 100 = 10%

1999: $\frac{350-320}{320}$ × 100 = 9.375%

2004: $\frac{370-350}{350}$ × 100 = 5.71%

2005: $\frac{420-370}{370}$ × 100 = 13.51%

Thus, the percentage change in the number of females over the previous year is the highest in 2005.

Hence, option (d).
