Which option shows correct understanding of keeping population growth and sex ratio separate?

Correct answer: वृद्धि संख्या में बदलाव है और लिंग अनुपात पुरुष महिला अनुपात बताता है

The direct answer is A. Population growth means a change in the total number of people living in a place over a period of time. It may be positive when the population increases or negative when it decreases. This change is influenced by births, deaths and migration. Sex ratio is a different idea: it describes the balance or relationship between females and males in a population. Therefore, growth measures change in population size, while sex ratio describes one part of population composition. B is wrong because the two indicators answer different questions. C is wrong because area means the size of land, usually measured in square kilometres, not the relationship between males and females. D is wrong because population growth includes people of all sexes, not only males. Memory cue: growth asks “how many people changed?”, while sex ratio asks “how are males and females represented?”
