Answer 1

The Correct Option is D

Step 1: Understanding the question.
The question asks for the major factors responsible for population change — i.e., the increase or decrease in population size over time.
Step 2: Explanation.
Population change occurs due to three main components:
1. Births (Natality): Increase population size.
2. Deaths (Mortality): Decrease population size.
3. Migration: Movement of people between regions — can increase or decrease the population of an area depending on inflow or outflow.
Step 3: Conclusion.
All three — birth, death, and migration — are components of population change. Hence, the correct answer is (D) All of these.
