First genetically modified plant commercially released in India is

Options

A. golden rice
B. Flavr savr
C. Bt brinjal
D. Bt cotton

Explanation

### Step-by-Step Solution:

1. **Understanding Genetically Modified Plants**:
- Genetically modified plants are those whose genetic material has been altered using biotechnology. This is typically done by inserting a new gene to achieve desired traits such as pest resistance, improved yield, or enhanced nutritional value.

2. **Identifying the Options**:
- The options provided are:
1. Golden Rice
2. Bt Brinjal
3. Bt Cotton
4. Flour

3. **Researching the First Commercial Release**:
- Among the options, it is important to identify which genetically modified plant was the first to be commercially released in India.

4. **Finding the Correct Answer**:
- The first genetically modified plant that was commercially released in India is **Bt Cotton**. This was developed by MAHYCO (Maharashtra Hybrid Seed Company) in collaboration with Monsanto, an American company.

5. **Understanding the Mechanism**:
- Bt Cotton has a gene from the bacterium Bacillus thuringiensis, which produces a toxin that is harmful to certain insects, particularly lepidopterans (like caterpillars). This toxin helps in protecting the cotton plant from pest damage.

6. **Conclusion**:
- Therefore, the correct answer to the question is **Bt Cotton**.
