Answer

To solve the matching question between Column A and Column B, we will identify the correct pairings based on the characteristics of each type of fungi listed in Column A.

### Step-by-Step Solution:

1. **Identify Fungi Imperfecti**:
- Fungi Imperfecti, also known as Deuteromycetes, are fungi that do not have a known sexual reproduction stage. Some of these fungi are known to cause yeast infections.
- **Match**: Fungi Imperfecti → (a) Yeast

2. **Identify Oomycetes**:
- Oomycetes are often referred to as water molds. They are not true fungi but share some characteristics with them. They are known for being aquatic and include organisms that resemble algae.
- **Match**: Oomycetes → (d) Water mould

3. **Identify Zygomycetes**:
- Zygomycetes are a group of fungi that includes species commonly known as bread molds. They reproduce sexually through zygospores.
- **Match**: Zygomycetes → (b) Bread mould

4. **Identify Ascomycetes**:
- Ascomycetes are a division of fungi known for producing spores in a sac-like structure called an ascus. Some Ascomycetes are responsible for causing ringworm infections in humans.
- **Match**: Ascomycetes → (c) Ringworm

5. **Identify Basidiomycetes**:
- Basidiomycetes are a taxonomic group of fungi that includes mushrooms and other fungi. One notable member, known as Puccinia graminis, is responsible for causing black rust of wheat.
- **Match**: Basidiomycetes → (e) Black rust of wheat

### Final Matches:
- Fungi Imperfecti → Yeast (a)
- Oomycetes → Water mould (d)
- Zygomycetes → Bread mould (b)
- Ascomycetes → Ringworm (c)
- Basidiomycetes → Black rust of wheat (e)
