Assertion: Population growth occurs not only by increasing births rate but also due to decreasing death rate.
Reasoning: Death rate plays an insignificant role in population change.
Answer & explanation
Correct answer: option 3
The correct answer is Option 3: Assertion (A) is true but Reasoning (R) is not correct.
Assertion: Population growth occurs not only by increasing births rate but also due to decreasing death rate. True. Population can grow either if more people are born, or if fewer people die (death rate falls).
Reasoning: Death rate plays an insignificant role in population change. False. Death rate plays a very significant role in population change. A fall in death rate (especially during early stages of development) is a major cause of rapid population growth.
