Question

Two statements are given below. They are Assertion (A) and Reason (R). Read both the statements carefully and choose the correct option.

Assertion (A) : The decades of 1951 – 1981 are referred to as the period of population explosion in India.

Reason (R) : This period was witnessed by rapid fall in mortality rate and high fertility rate of the population.

• A. Assertion (A) is correct, but Reason (R) is incorrect.
• B. Assertion (A) is incorrect, but Reason (R) is correct.
• C. Both Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A).
• D. Both Assertion (A) and Reason (R) are correct, but Reason (R) is not the correct explanation of Assertion (A).

Hint:

In 1951-1981 death rate fell fast and birth rate stayed high, causing population explosion. R explains A.

Answer 1

The Correct Option is C

Step 1: Understand the concept:
Population explosion means a very fast rise in population. This happens when death rate falls quickly but birth rate stays high.

Step 2: Check Assertion (A):
NCERT calls the decades 1951-1981 the period of population explosion in India. So (A) is TRUE.

Step 3: Check Reason (R):
After independence, health care, sanitation and food supply improved, so mortality fell fast. Fertility stayed high. So (R) is TRUE.

Step 4: Does R explain A?:
A fast fall in death rate with high birth rate leaves a big gap between births and deaths. The gap is the explosion. So (R) explains (A).

Step 5: Why the other options are wrong:
(A) and (B) call one true statement false. (D) says R is not the reason, but it is the main reason.

Final Answer:
Both A and R are correct and R is the correct explanation, option (C).
