Which one of the following is a correct statement ?

Options

A. 'Bt'' in '' Bt - cotton'' indicates that it is a genetically modified organism produced through biotechnology
B. Somatic hybridization involves fusion of two complete plant cells carrying desired genes.
C. The transgenic Brassica napus seeds are used for production of antibiotics .
D. 'FlavrSavr'' variety of tomato has enhanced the production of ethylene which improves its taste .

Answer

To solve the question regarding which statement is correct, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Evaluate Option 1:**
- The statement claims that "Bt in Bt cotton indicates that it is a genetically modified organism produced through biotechnology."
- **Analysis:** Bt stands for Bacillus thuringiensis, a bacterium that produces proteins toxic to certain insects. Bt cotton is indeed genetically modified to express these proteins, making this statement true.

2. **Evaluate Option 2:**
- The statement discusses somatic hybridization, stating that it involves the fusion of two complete plant cells.
- **Analysis:** Somatic hybridization involves the fusion of protoplasts (the plant cells without their cell walls), not complete cells. Therefore, this statement is false.

3. **Evaluate Option 3:**
- The statement mentions that the seeds of Transgenic Brassica napus are used for the production of antibiotics.
- **Analysis:** Transgenic Brassica napus is known for producing anticoagulants like hirudin, not antibiotics. This statement is also false.

4. **Evaluate Option 4:**
- The statement claims that the flavor-savory variety of tomato enhances ethylene production, improving its taste.
- **Analysis:** Flavor-savor tomatoes are genetically engineered to delay softening by inhibiting the polygalacturonase enzyme, which does not directly enhance ethylene production for taste improvement. Thus, this statement is false.

### Conclusion:
After analyzing all the options, the only correct statement is from **Option 1**.

### Final Answer:
**The correct statement is Option 1.**
