Choose an option with the correct statements from the list below `:`
i. The telomere is heterochromatic in nature.
ii. The telocentric chromosome has centromere close to its end.
iii. Satellite is located near primary constriction.
iv. Submetacentric chromosomes are L-shaped.

Options

A. i & ii
B. ii & iii
C. iii & iv
D. i, iii and & iv

Answer

To solve the question, we need to evaluate each statement regarding chromosomes and determine which ones are correct.

### Step-by-Step Solution:

1. **Evaluate Statement i**: "The telomere is heterochromatic in nature."
- **Analysis**: Telomeres are indeed composed of heterochromatin, which is genetically inactive. This statement is correct.

2. **Evaluate Statement ii**: "The telocentric chromosome has a centromere close to its end."
- **Analysis**: A telocentric chromosome has its centromere located at one of its ends, not just close to the end. Therefore, this statement is incorrect.

3. **Evaluate Statement iii**: "Satellite is located near primary constriction."
- **Analysis**: Satellites are indeed found near the primary constriction (centromere) of chromosomes. This statement is correct.

4. **Evaluate Statement iv**: "Submetacentric chromosomes are L-shaped."
- **Analysis**: Submetacentric chromosomes have a centromere that is off-center, resulting in two arms of unequal length, which can give them an L-shape appearance. This statement is also correct.

### Summary of Correct Statements:
- Statement i: Correct
- Statement ii: Incorrect
- Statement iii: Correct
- Statement iv: Correct

### Conclusion:
The correct statements are i, iii, and iv. Therefore, the option that includes statements 1, 3, and 4 is the correct answer.

### Final Answer:
The correct option is **4** (statements i, iii, and iv are correct).
