Which factor is listed as affecting population growth?

• A. Climate variability
• B. Postponement of marriage
• C. Solar activity
• D. Oceans currents

Answer: (B)

The timing of childbearing is a major determinant of population growth. When people postpone marriage, they enter their reproductive years later, which reduces the number of years available for having children. This typically lowers the total number of births per woman and slows overall population growth. Other options—climate variability, solar activity, and ocean currents—affect the environment and resources but do not directly determine how many children a population tends to have. So postponing marriage is the factor that most directly influences population growth among the choices.
