Match the Column I with Column II -
`{:(" Column I"," Column II"),("I. Endothermic animals","A. Angler fish"),("II. Ectothermal animals","B. Mammals"),("III. Organisms of benthonic zone","C. Amphibia, reptiles"):}`

Options

A. `{:("I","II","III"),("A","B","C"):}`
B. `{:("I","II","III"),("C","B","A"):}`
C. `{:("I","II","III"),("B","C","A"):}`
D. `{:("I","II","III"),("A","C","B"):}`

Answer

To solve the matching question between Column I and Column II, we need to understand the definitions of the terms in Column I and match them with the appropriate terms in Column II.

### Step-by-Step Solution:

1. **Identify Endothermic Animals**:
- Endothermic animals are those that can regulate their body temperature internally, regardless of the environment.
- Common examples include mammals and birds.

**Match**:
- I. Endothermic animals → B. Mammals

2. **Identify Ectothermal Animals**:
- Ectothermal animals, also known as poikilothermic animals, rely on external environmental conditions to regulate their body temperature.
- Common examples include amphibians and reptiles.

**Match**:
- II. Ectothermal animals → C. Amphibia, reptiles

3. **Identify Organisms of the Benthonic Zone**:
- The benthonic zone refers to the ecological region at the lowest level of a body of water, including the sediment surface and sub-surface layers.
- Angler fish are known to inhabit deep-sea environments and are often found in the benthic zone.

**Match**:
- III. Organisms of benthonic zone → A. Angler fish

### Final Matches:
- I → B (Endothermic animals → Mammals)
- II → C (Ectothermal animals → Amphibia, reptiles)
- III → A (Organisms of benthonic zone → Angler fish)

### Summary of Matches:
- I. Endothermic animals → B. Mammals
- II. Ectothermal animals → C. Amphibia, reptiles
- III. Organisms of benthonic zone → A. Angler fish
