Options

A. `A-(iii),B-(iv),C-(i),D-(v)`
B. `A-(iv),B-(iii),C-(iv),D-(i)`
C. `A-(ii),B-(i),C-(v),D-(iv)`
D. `A-(iii),B-(ii),C-(i),D-(iv)`

Answer

To solve the problem of matching Column I with Column II, we need to analyze each item in Column I and determine the type of interaction it represents from Column II. Here's the step-by-step breakdown:

### Step 1: Analyze "Ladybird beetles feeding on insects"
- **Type of Interaction**: This describes a situation where one organism (the ladybird beetle) feeds on another organism (insects).
- **Conclusion**: This is an example of **Predation**, where the predator benefits by obtaining food, while the prey is harmed.
- **Match**: A → (ii) Predation

### Step 2: Analyze "Barnacles growing on the back of a whale"
- **Type of Interaction**: In this case, barnacles attach themselves to a whale. The whale is not harmed, but the barnacles benefit from mobility and access to food.
- **Conclusion**: This is an example of **Commensalism**, where one species benefits and the other is neither helped nor harmed.
- **Match**: B → (iv) Commensalism

### Step 3: Analyze "Wasp pollinating the fig inflorescence"
- **Type of Interaction**: The wasp pollinates the fig and, in return, receives nectar and a place to lay its eggs. Both the wasp and the fig benefit from this interaction.
- **Conclusion**: This is an example of **Mutualism**, where both species benefit from the interaction.
- **Match**: C → (i) Mutualism

### Step 4: Analyze "Lice living on skin of humans"
- **Type of Interaction**: Lice feed on human blood, deriving nutrition while harming the host.
- **Conclusion**: This is an example of **Parasitism**, where the parasite benefits at the expense of the host.
- **Match**: D → (v) Parasitism

### Final Matching Summary:
- A → (ii) Predation
- B → (iv) Commensalism
- C → (i) Mutualism
- D → (v) Parasitism

### Conclusion:
The correct matches are:
- A - (ii)
- B - (iv)
- C - (i)
- D - (v)

Thus, the correct answer is option A.
