Match the column I and II
`{:("Column I", "Column II"),("(i) Chrysophyte", "(a) Gonyaulax"),("(ii) Dinoflagellate","(b) Euglena"),("(iii) Euglenoids", "(c) Diatom"),("(iv) Slime moulds", "(d) Plasmodium"):}`

Options

A. i – a, ii – c, iii – b, iv – d
B. i – a, ii – d, iii – b, iv – c
C. i – c, ii – b, iii – d, iv – a
D. i – c, ii – a, iii – b, iv – d

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find its corresponding match in Column II based on their characteristics and examples.

### Step-by-Step Solution:

1. **Identify Chrysophytes:**
- Chrysophytes are commonly known as golden algae. They are a large group of algae found in freshwater and include diatoms and yellow-green algae.
- **Match:** Chrysophyte (i) → Diatom (c)

2. **Identify Dinoflagellates:**
- Dinoflagellates are a group of flagellate eukaryotes, and a common example is Gonyaulax, which is known for causing red tides in oceans.
- **Match:** Dinoflagellate (ii) → Gonyaulax (a)

3. **Identify Euglenoids:**
- Euglenoids are single-celled flagellate eukaryotes commonly found in freshwater. A well-known example is Euglena.
- **Match:** Euglenoids (iii) → Euglena (b)

4. **Identify Slime Molds:**
- Slime molds consist of a gelatinous mass of protoplasm and are known for their amoeba-like characteristics. A common example is Plasmodium, which is an obligate parasite.
- **Match:** Slime molds (iv) → Plasmodium (d)

### Final Matching:
- (i) Chrysophyte → (c) Diatom
- (ii) Dinoflagellate → (a) Gonyaulax
- (iii) Euglenoids → (b) Euglena
- (iv) Slime molds → (d) Plasmodium

### Answer:
The correct matching is:
- (i) → (c)
- (ii) → (a)
- (iii) → (b)
- (iv) → (d)

Thus, the final answer is **C, A, B, D**.
