Answer

To solve the question regarding which plant flowers only once in its life after 50-100 years, produces a large number of fruits, and then dies, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Understand the Question**:
- The question specifies a plant that flowers only once in its lifetime, typically after a long period (50-100 years), produces a large number of fruits, and then dies.

2. **Evaluate Option 1: Strobilanthus kuntiana**:
- This plant, also known as Neel Kurunchi, has a flowering cycle of every 12 years.
- Since it does not meet the criteria of flowering after 50-100 years, this option is **not correct**.

3. **Evaluate Option 2: Bamboo**:
- Bamboo is known to flower after a long period, typically between 50 to 100 years.
- It produces a large number of seeds (fruits) and then dies after flowering.
- This option perfectly satisfies the conditions mentioned in the question, making it **the correct option**.

4. **Evaluate Option 3: Calistemon linearis**:
- This plant flowers annually during spring and early summer.
- It does not have a unique flowering pattern that corresponds with the question's criteria, so this option is **not correct**.

5. **Evaluate Option 4: Sympogon reptocus**:
- This plant rarely flowers and does not follow a specific flowering pattern.
- Therefore, it does not meet the criteria given in the question, making this option **not correct**.

### Conclusion:
After evaluating all the options, the only plant that meets the criteria of flowering once in its lifetime after 50-100 years, producing a large number of fruits, and then dying is **Option 2: Bamboo**.
