The net reproduction rate (NRR) is defined as the average number of daughters a woman would have in her lifetime if she were subject to the prevailing age-specific fertility and mortality rates throughout her life. It is calculated as the sum of the products of the age-specific fertility rate (m) and the proportion of women surviving to each age (l), across all reproductive ages. Thus, choice C, which represents this concept as ∑ l_x m_x, is correct.
