Option 1 states that both the Assertion (A) and Reason (R) are true and that the Reason is the correct explanation for the Assertion. However, this option is incorrect.

Option 2 states that both the Assertion (A) and Reason (R) are true, but the Reason is not a correct explanation for the Assertion. This option is correct.

Option 3 states that the Assertion (A) is true, but the Reason (R) is false. This option is the correct answer.

Option 4 states that the Assertion (A) is false, but the Reason (R) is true. This option is incorrect.

The correct answer, option 3, indicates that while the Assertion is true (millions of people in our country are below the poverty line), the Reason is false (food production is not necessarily low in the country).

Food production may or may not be a contributing factor to poverty, but it is not the only reason for people being below the poverty line. There are other factors such as unemployment, lack of education, unequal distribution of wealth, etc. that can also contribute to poverty.
