Correct Answer:
B. Demography
The study of human populations is a specialized field that examines various aspects of how populations change over time. This scientific discipline provides crucial insights into societal trends, resource allocation, and future planning.
- B: Demography is the correct answer. Demography is the statistical study of human populations, focusing on their size, structure, distribution, and how these change over time due to births, deaths, migration, and aging.
- A: Geography is the study of the Earth's physical features and atmosphere, and human activity as it affects and is affected by these. While it can include population distribution, it's broader than just population study.
- C: Polygraphy refers to the use of a polygraph (lie detector) or the art of writing in various styles, unrelated to population study.
- D: Biography is an account of someone's life written by someone else, focusing on an individual rather than a population.
Therefore, demography is the precise term for the study of human population dynamics.
