C. a(iii), b(iv), c(i), d(ii), e(v)
D. a(i), b(iii), c(ii), d(iv), e(v)

Answer

To solve the matching question, we will analyze each item in Column I and find the appropriate match in Column II based on the definitions and characteristics of the organisms mentioned.

### Step-by-Step Solution:

1. **Identify Mixotrophic Protist**:
- A mixotrophic protist is one that can perform both autotrophic (photosynthesis) and heterotrophic (ingesting food) nutrition.
- Among the options in Column II, **Euglena** is known for its ability to photosynthesize as well as consume organic matter.
- **Match**: a. Mixotrophic protist - (iii) Euglena

2. **Identify Plasmodial Slime Mould**:
- Plasmodial slime moulds are characterized by a large, multinucleate cell (plasmodium) that can move and engulf food.
- **Physarum** is a well-known example of a plasmodial slime mould.
- **Match**: b. Plasmodial slime mould - (iv) Physarum

3. **Identify Holozoic Protist**:
- Holozoic protists are those that ingest solid food, typically by engulfing it.
- **Peranema** is a protist that exhibits holozoic nutrition by engulfing food particles.
- **Match**: c. Holozoic protist - (i) Peranema

4. **Identify Saprobic Protist**:
- Saprobic protists feed on dead and decaying organic matter.
- **Polysphondylium** is a saprobic protist that belongs to the group of cellular slime moulds.
- **Match**: d. Saprobic protist - (ii) Polysphondylium

5. **Identify Communal Slime Mould**:
- Communal slime moulds are those that live in a community association.
- **Rhabdomonas** is known to exist in communal associations.
- **Match**: e. Communal slime mould - (v) Rhabdomonas

### Final Matches:
- a. Mixotrophic protist - (iii) Euglena
- b. Plasmodial slime mould - (iv) Physarum
- c. Holozoic protist - (i) Peranema
- d. Saprobic protist - (ii) Polysphondylium
- e. Communal slime mould - (v) Rhabdomonas

### Summary of Matches:
- A - iii
- B - iv
- C - i
- D - ii
- E - v
