Match the following :
`{:(,"Column I","Column II"),(A,"Chrysophtes","i the pigments are identical those of higher plants "),(B,"Dinoflagellates","ii. float passively in water current"),(C,"Euglenoids","iii have two flagella"):}`

Options

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

Answer

To solve the matching question, we need to analyze each organism in Column I and find the corresponding description in Column II.

### Step-by-Step Solution:

1. **Identify Chrysophytes:**
- Chrysophytes are primarily non-motile organisms. They possess flagella but do not actively swim; instead, they float passively in water currents.
- **Match:** Chrysophytes → ii. float passively in water current.

2. **Identify Dinoflagellates:**
- Dinoflagellates are unicellular eukaryotes that have two flagella. These flagella are unequal, with one being transverse and the other vertical.
- **Match:** Dinoflagellates → iii. have two flagella.

3. **Identify Euglenoids:**
- Euglenoids are aquatic organisms that can perform photosynthesis due to the presence of chloroplasts, which contain pigments identical to those found in higher plants.
- **Match:** Euglenoids → i. the pigments are identical to those of higher plants.

### Final Matches:
- A (Chrysophytes) → ii (float passively in water current)
- B (Dinoflagellates) → iii (have two flagella)
- C (Euglenoids) → i (the pigments are identical to those of higher plants)

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