Options

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

Answer

To solve the matching question, we will analyze each type of root mentioned in Column I and identify the corresponding plant from Column II.

### Step-by-Step Solution:

1. **Floating Roots**:
- **Definition**: These roots are modified to help the plant float. They contain air spaces that provide buoyancy.
- **Matching Plant**: Jussiaea is known for having floating roots.
- **Match**: a - (iv) Jussiaea

2. **Assimilatory Roots**:
- **Definition**: These roots are involved in photosynthesis, allowing the plant to produce its own food.
- **Matching Plant**: Podostemon is known for its assimilatory roots.
- **Match**: b - (i) Podostemon

3. **Hygroscopic Roots**:
- **Definition**: These roots absorb moisture from the air rather than from the soil.
- **Matching Plant**: Orchids have hygroscopic roots that help them absorb water from the atmosphere.
- **Match**: c - (v) Orchids

4. **Haustorial Roots**:
- **Definition**: These roots penetrate the host plant to extract nutrients, typically found in parasitic plants.
- **Matching Plant**: Cuscuta is a parasitic plant that uses haustorial roots to draw nutrients from its host.
- **Match**: d - (ii) Cuscuta

5. **Epiphylous Roots**:
- **Definition**: These roots grow from the leaves and are adapted to absorb moisture and nutrients directly from the air.
- **Matching Plant**: Bryophyllum has epiphylous roots that grow from its leaves.
- **Match**: e - (iii) Bryophyllum

### Final Matches:
- a - (iv) Jussiaea
- b - (i) Podostemon
- c - (v) Orchids
- d - (ii) Cuscuta
- e - (iii) Bryophyllum

### Summary of Matches:
- a → iv
- b → i
- c → v
- d → ii
- e → iii
