A : Biofortified crops such as golden rice are helpful in overcoming the problem of night blindness in developing nations.
R : It has enhanced nutritional content of vitamin A.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1 )
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4).

Answer

**Step-by-Step Solution:**

1. **Understanding the Problem:**
- Night blindness is a condition caused by a deficiency of vitamin A. It is prevalent in many developing nations where diets may lack sufficient nutrients.

2. **Introduction to Biofortified Crops:**
- Biofortified crops are genetically modified to enhance their nutritional content. One such example is golden rice.

3. **Golden Rice and Genetic Modification:**
- Golden rice has been genetically engineered to contain a gene that produces beta-carotene, a precursor to vitamin A. This modification allows the rice to have a higher nutritional value.

4. **Linking Golden Rice to Night Blindness:**
- Since night blindness is caused by a deficiency of vitamin A, and golden rice is enriched with beta-carotene (which the body converts to vitamin A), it can help alleviate this deficiency.

5. **Conclusion:**
- Therefore, the statement that biofortified crops like golden rice are helpful in overcoming night blindness is true. The reason provided, that it has enhanced nutritional content of vitamin A, is also true and serves as a correct explanation for the first statement.

**Final Answer:**
- Both statements A and R are true, and R is the correct explanation of A.
