Given below are some applications of biotechnology for which all other statements are correct , except ?

Options

A. Biotechnology enable us to create tailor made plants to supply of alternative resources to industries
B. Production of pest resistant plants that could decrease the pesticide use
C. Biotechology has enhanced nutritional value of food crops
D. Biotechonolgy helped in maintaining ecological balance of environment

Answer

### Step-by-Step Solution:

1. **Understanding Biotechnology**:
- Biotechnology is a branch of applied sciences that involves the use of living organisms and their derivatives to create new products and processes. This includes genetic engineering, which modifies organisms for specific purposes.

2. **Analyzing the Statements**:
- **Statement 1**: "Biotechnology enables us to create tailor-made plants to supply alternative resources to industries."
- This statement is correct. Tailor-made plants are genetically modified to produce high yields and resist diseases, supplying resources like fuels and pharmaceuticals.

- **Statement 2**: "Production of pest-resistant plants that could decrease pesticide use."
- This statement is also correct. Pest-resistant plants, such as Bt cotton, are developed through genetic engineering to reduce the need for chemical pesticides.

- **Statement 3**: "Biotechnology has enhanced the nutritional value of food crops."
- This statement is correct. An example is golden rice, which is genetically modified to be rich in vitamin A, enhancing its nutritional value.

- **Statement 4**: "Biotechnology helped in maintaining ecological balance of the environment."
- This statement is incorrect. While biotechnology has many benefits, it does not directly contribute to maintaining ecological balance, and in some cases, it can disrupt ecosystems.

3. **Conclusion**:
- The statement that is not correct among the given options is the last one: "Biotechnology helped in maintaining ecological balance of the environment."

### Final Answer:
The statement that is incorrect is: "Biotechnology helped in maintaining ecological balance of the environment."
