Which of the following argricultural challenges cannot be solved with transgenic techniques ?

Options

A. Crops are damaged by frost or drought
B. Crops are damaged by insect pests
C. Public concern about safety of synthetic pesticides
D. Public preference for organic vegetables

Answer

**Step-by-Step Solution:**

1. **Understanding Transgenic Techniques:**
- Transgenic techniques involve the genetic modification of organisms, specifically plants in this context. This is done by altering the genetic makeup through the insertion or deletion of specific genes.

2. **Identifying Agricultural Challenges:**
- The question asks which agricultural challenges cannot be addressed by transgenic techniques. Common challenges include:
- Resistance to abiotic stresses (e.g., drought, salinity, temperature).
- Resistance to pests and insects.
- Concerns about the safety of synthetic pesticides.
- Public preference for organic vegetables.

3. **Analyzing Each Challenge:**
- **Abiotic Stress Resistance:** Transgenic techniques can create crops that are resistant to drought, salinity, and temperature extremes.
- **Pest Resistance:** Genetic modification can enhance a plant's ability to resist pests and insects, thus increasing yield.
- **Synthetic Pesticide Safety:** Transgenic crops can reduce reliance on synthetic pesticides, addressing public safety concerns.
- **Organic Vegetable Preference:** This challenge is related to consumer choice and preference for organic farming practices, which typically do not involve genetic modification.

4. **Conclusion:**
- Among the options listed, the challenge that cannot be solved with transgenic techniques is the public preference for organic vegetables. This preference is rooted in consumer choice rather than a technical agricultural challenge that can be addressed through genetic modification.

**Final Answer:**
- The agricultural challenge that cannot be solved with transgenic techniques is the public preference for organic vegetables.
