Read the given statements and select the correct option.
(i) Darwin and Darwin (1880) found that sensation of unilateral illumination was perceived by the coleoptile tip of canary grass.
(ii) IA A is universal natural auxin, discovered by Kogi et al.
(iii) IBA is both natural and synthetic auxin.
(iv) Auxins promote the growth of lateral shoots.

Options

A. statements (i) and (ii) are correct.
B. statements (ii) and (iii) are correct
C. Statements (i), (ii) and (iii) are correct
D. Statements (i),(ii),(iii) and (iv) are correct.

Explanation

To solve the question, we need to evaluate each of the statements provided and determine which ones are correct.

### Step-by-Step Solution:

1. **Evaluate Statement (i)**:
- "Darwin and Darwin (1880) found that sensation of unilateral illumination was perceived by the coleoptile tip of canary grass."
- This statement is **correct**. Darwin and his son conducted experiments that demonstrated how the coleoptile tip of canary grass responds to light, indicating that the tip is responsible for perceiving light direction.

**Hint**: Remember the role of the coleoptile tip in phototropism.

2. **Evaluate Statement (ii)**:
- "IAA is universal natural auxin, discovered by Kogi et al."
- This statement is also **correct**. IAA (Indole-3-acetic acid) is indeed a natural auxin found in plants and is considered universal because it is widely present in various plant species.

**Hint**: Focus on the definition of natural auxins and their discovery.

3. **Evaluate Statement (iii)**:
- "IBA is both natural and synthetic auxin."
- This statement is **correct**. Indole-3-butyric acid (IBA) was initially synthesized artificially but has also been found in plants, making it both a natural and synthetic auxin.

**Hint**: Consider how some compounds can be both synthesized and naturally occurring.

4. **Evaluate Statement (iv)**:
- "Auxins promote the growth of lateral shoots."
- This statement is **incorrect**. Auxins are known to promote apical dominance, where the growth of the apical bud inhibits the growth of lateral buds, thus reducing the growth of lateral shoots.

**Hint**: Recall the concept of apical dominance and its effect on lateral shoot growth.

### Conclusion:
Based on the evaluation:
- Statements (i), (ii), and (iii) are correct.
- Statement (iv) is incorrect.

Thus, the correct option includes statements 1, 2, and 3.

### Final Answer:
The correct option is the one that includes statements (i), (ii), and (iii).
