Match column I with column II and select the correct option from the codes given below.
`{:(Column I, Column II),(("Phytohotomne"),"(Plant part where it is synthesised)"),(A.I A A,(i)"Tissues undergoing senescence "),(B."Cytokinins",(ii)"Shoot apices"),(C."Ethylene",(iii)"Root apices"):}`

Options

A. A-(ii),B-(iii),C-(i)
B. A-(iii),B-(ii),C-(i)
C. A-(i),B-(ii),C-(iii)
D. A-(ii),B-(i),C-(iii)

Answer

To solve the matching question, we need to correctly associate each phytohormone from Column I with the corresponding plant part where it is synthesized from Column II.

### Step-by-Step Solution:

1. **Identify the Phytohormones**:
- We have three phytohormones:
- A. IAA (Indole-3-acetic acid)
- B. Cytokinins
- C. Ethylene

2. **Determine the Plant Parts**:
- The possible plant parts where these hormones are synthesized are:
- (i) Tissues undergoing senescence
- (ii) Shoot apices
- (iii) Root apices

3. **Match IAA (Indole-3-acetic acid)**:
- IAA is primarily involved in promoting stem elongation and is synthesized in the shoot apices and root tips. Therefore, the correct match for IAA is:
- **Match A (IAA)** with **(ii) Shoot apices**.

4. **Match Cytokinins**:
- Cytokinins are produced in the root apical meristem and are involved in promoting cell division. Hence, the correct match for Cytokinins is:
- **Match B (Cytokinins)** with **(iii) Root apices**.

5. **Match Ethylene**:
- Ethylene is known for its role in the ripening of fruits and is produced in tissues undergoing senescence. Thus, the correct match for Ethylene is:
- **Match C (Ethylene)** with **(i) Tissues undergoing senescence**.

### Final Matches:
- A. IAA → (ii) Shoot apices
- B. Cytokinins → (iii) Root apices
- C. Ethylene → (i) Tissues undergoing senescence

### Summary of Matches:
- A → (ii)
- B → (iii)
- C → (i)
