The approximate number of genes contained in the genome of Kalpana Chawla was

Options

A. `40,000`
B. `30,000`
C. `80,000`
D. `1,00,000`

Answer

To determine the approximate number of genes contained in the genome of Kalpana Chawla, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Human Genome**: The human genome is composed of approximately 21,000 genes. This is a well-established figure based on extensive genomic research.

2. **Identify the Context**: Kalpana Chawla was a human being, so her genome would also fall within the same range as the human genome.

3. **Consider the Options Provided**: The options given were 40,000, 30,000, 80,000, and 1 lakh. We need to find the option that is closest to the known number of human genes.

4. **Analyze the Options**:
- 40,000 is significantly higher than the known number of human genes.
- 30,000 is slightly higher than 21,000 but is the closest option.
- 80,000 and 1 lakh are much higher than the known number of genes.

5. **Conclusion**: Since Kalpana Chawla is human, and the approximate number of genes in humans is around 21,000, the closest option provided is 30,000. Therefore, the approximate number of genes contained in the genome of Kalpana Chawla is 30,000.

### Final Answer:
The approximate number of genes contained in the genome of Kalpana Chawla was **30,000**.
