If a country’s total fertility rate (TFR) is measured at 1, what does this number most likely indicate about the country’s population?

A total fertility rate of 1 means that, on average, each woman has one child over her lifetime—well below the roughly 2.1 children per woman needed to replace the population in many countries. With fewer children entering the population, the average age tends to rise over time. Therefore, the best answer is that the country’s population is aging; the figure does not indicate population growth or a much higher birth rate than death rate.
