The correct Answer is:
To determine which statements about genetically modified plants are correct, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement (a): Enhanced nutritional value of food.** - Genetically modified plants can be engineered to have enhanced nutritional profiles. A prime example is golden rice, which has been modified to contain beta-carotene, a precursor to vitamin A. This modification increases the nutritional value of the food produced. - **Conclusion**: This statement is **correct**. 2. **Statement (b): Decreased efficiency of mineral usage by plants.** - Genetically modified plants are often designed to utilize minerals more efficiently, not less. They can be engineered to improve nutrient uptake and usage, which enhances their growth and development. - **Conclusion**: This statement is **incorrect**. 3. **Statement (c): Increased reliance on chemical pesticides.** - Genetically modified plants are often developed to be resistant to pests, which can reduce the need for chemical pesticides. For instance, some GM crops are engineered to produce their own pest resistance, decreasing reliance on external chemical treatments. - **Conclusion**: This statement is **incorrect**. 4. **Statement (d): Reduced post-harvest losses.** - Genetically modified plants can be designed to have traits that reduce spoilage and enhance shelf life, leading to reduced post-harvest losses. This is beneficial in maintaining food supply and reducing waste. - **Conclusion**: This statement is **correct**. ### Final Assessment: Based on the analysis: - Correct statements: (a) Enhanced nutritional value of food and (d) Reduced post-harvest losses. - Incorrect statements: (b) Decreased efficiency of mineral usage by plants and (c) Increased reliance on chemical pesticides. Thus, the correct statements are **(a) and (d)**.
