Hint:
This hypothesis is an area of research, focused on a consideration of their evolutionary history, dealing with the exact prediction of proportion of all sexual beings. Exposure to pesticides and other environmental toxins may be important in this setting.

Complete Answer:
 The number of females in the population per 1,000 males is considered the sex ratio. The sex ratio is the percentage of males to females in a population. The ratio appears to be 1:1 in most animals that reproduce sexually. This trend is clarified by Fisher's theory. However for different reasons, many animals deviate, either regularly or permanently, from doing something approaching an equal sex ratio. The sex ratio is defined as the population's number of females per 1000 males. This knowledge is an important social measure for assessing at a given time the level of equality between men and women in a society. The country's sex ratio has still been negative for women. An significant statistic about the role of women in a country is the sex ratio. The sex ratio is bound to be unfavourable for women in areas where gender inequality is rampant. The culture of female foeticide, female infanticide and domestic abuse against women was widespread in such regions. Women's lower socio-economic standing in these places may be one of the reasons. You must note that in the population, more women do not mean that they have a greater status. It may be that the men would have moved for jobs to other places.

Hence, the correct answer is option D.

Note:
This knowledge is an important social measure for assessing at a given time the level of equality between men and women in a society. It is used to analyze other data types and to assess the completeness and accuracy of population counts.
