Match the following with correct combination
`{:("Column-I","Column-II"),("A Mutualism","1 Tiger and deer"),("B Commensalism","2 Cuscuta on Cissus"),("C Parasitism","3 Suckerfish and shark"),("D Predation","4 Crab and sea anemone"):}`

Options

A. A – 1, B – 2, C – 3, D – 4
B. A – 4, B – 3,C – 2,D – 1
C. A – 1, B – 3, C – 2, D – 4
D. A – 2, B –3, C – 1, D –4

Explanation

To solve the matching question, we need to understand the definitions of the ecological relationships in Column-I and find the appropriate examples in Column-II. Let's break it down step by step:

### Step 1: Understand Mutualism
- **Definition**: Mutualism is a symbiotic relationship where both species benefit from the interaction.
- **Example from Column-II**: The correct example for mutualism is "Crab and sea anemone". In this relationship, the crab gets protection from predators while the sea anemone gets food scraps from the crab.

### Step 2: Understand Commensalism
- **Definition**: Commensalism is a relationship where one species benefits while the other is neither helped nor harmed.
- **Example from Column-II**: The correct example for commensalism is "Suckerfish and shark". The suckerfish attaches to the shark for transportation and feeding, while the shark remains unaffected.

### Step 3: Understand Parasitism
- **Definition**: Parasitism is a relationship where one organism (the parasite) benefits at the expense of the other (the host), often harming it in the process.
- **Example from Column-II**: The correct example for parasitism is "Cuscuta on Cissus". Cuscuta is a parasitic plant that derives nutrients from the host plant Cissus.

### Step 4: Understand Predation
- **Definition**: Predation is a relationship where one organism (the predator) kills and eats another organism (the prey).
- **Example from Column-II**: The correct example for predation is "Tiger and deer". The tiger hunts and eats the deer.

### Final Matching
Now, we can summarize the correct matches:
- A (Mutualism) → 4 (Crab and sea anemone)
- B (Commensalism) → 3 (Suckerfish and shark)
- C (Parasitism) → 2 (Cuscuta on Cissus)
- D (Predation) → 1 (Tiger and deer)

### Conclusion
The correct combinations are:
- A - 4
- B - 3
- C - 2
- D - 1
