`{:(,"Column-I",,"Column-II"),("(A)","Pistils fused together","(i)","Gametogenesis"),("(B)","Formation of gametes","(ii)","Pistillate"),("(C)","Hyphae of higher Ascomycetes","(iii)","Syncarpous"),("(D)","Unisexual female flower","(iv)","Dikaryotic"):}`

Options

A. `{:(A,B,C,D),(4,3,2,1):}`
B. `{:(A,B,C,D),(2,1,4,3):}`
C. `{:(A,B,C,D),(1,2,4,3):}`
D. `{:(A,B,C,D),(3,1,4,2):}`

Explanation

To solve the matching question, we need to analyze each item in Column-I and find its corresponding match in Column-II. Let's go through each option step by step.

### Step-by-Step Solution:

1. **Option A: Pistils fused together**
- The term "pistils fused together" refers to a condition where the carpels (female reproductive structures) of a flower are joined. This condition is known as **Syncarpous**.
- **Match:** A → (iii) Syncarpous

2. **Option B: Formation of gametes**
- The process of forming gametes is called **Gametogenesis**. This is the biological process through which gametes (sperm and eggs) are produced.
- **Match:** B → (i) Gametogenesis

3. **Option C: Hyphae of higher Ascomycetes**
- In higher Ascomycetes, the hyphae can exist in a stage where they have two nuclei, which is referred to as **Dikaryotic**. This is a characteristic stage in the life cycle of these fungi.
- **Match:** C → (iv) Dikaryotic

4. **Option D: Unisexual female flower**
- A flower that contains only female reproductive structures (pistils) is termed **Pistillate**. This is indicative of a unisexual flower that is female.
- **Match:** D → (ii) Pistillate

### Final Matches:
- A → (iii) Syncarpous
- B → (i) Gametogenesis
- C → (iv) Dikaryotic
- D → (ii) Pistillate

### Conclusion:
The correct option that matches all pairs is:
- A → (iii)
- B → (i)
- C → (iv)
- D → (ii)

Thus, the answer is option 4.
