Genetic modification has
I) reduced reliance on chemical pesticides.
II) reduced post-harvest losses.
III) increased efficiency of minerals used by the plants.
IV) enhanced nutritional value of the food.
Which of the statements given above are correct?

Options

A. I, II, III and IV
B. I, II and III
C. II, III and IV
D. III and IV

Answer

To determine which statements about genetic modification are correct, let's analyze each statement step by step:

### Step 1: Analyze Statement I
**Statement I: Genetic modification has reduced reliance on chemical pesticides.**
- Genetic modification has indeed led to the development of crops that are resistant to pests. For example, Bt cotton and Bt corn are genetically modified to produce a toxin that is harmful to specific insects, reducing the need for chemical pesticides.
- **Conclusion:** This statement is correct.

### Step 2: Analyze Statement II
**Statement II: Genetic modification has reduced post-harvest losses.**
- Genetic modification can enhance the shelf life of certain crops. For instance, genetically modified tomatoes have been developed to resist decay and spoilage after harvest, thus reducing post-harvest losses.
- **Conclusion:** This statement is correct.

### Step 3: Analyze Statement III
**Statement III: Genetic modification has increased efficiency of minerals used by the plants.**
- Genetic modification can improve the nutrient uptake of plants, allowing them to utilize minerals more efficiently. This can lead to better growth and yield without depleting soil nutrients too quickly.
- **Conclusion:** This statement is correct.

### Step 4: Analyze Statement IV
**Statement IV: Genetic modification has enhanced nutritional value of the food.**
- Many genetically modified crops are biofortified to enhance their nutritional content. For example, Golden Rice is genetically modified to contain higher levels of Vitamin A, addressing nutritional deficiencies in certain populations.
- **Conclusion:** This statement is correct.

### Final Conclusion
All four statements regarding genetic modification are correct. Therefore, the answer is that all statements (I, II, III, and IV) are correct.

### Summary of Correct Statements
- I) Correct
- II) Correct
- III) Correct
- IV) Correct
