Prashant categorised living organisms on the basis of their habitats. He made four groups of four organisms each. By mistake he placed one wrong member in each group. Identify the wrong member and select the correct option.
Group I : Meerkat, Fennec fox, Camel, Penguin
Group II : Polar bear, Musk ox, Blackbuck, Caribou Group
III : Carp, Climbing perch, Arowana, Sloth Group
IV : White oryx, Toucan, Lion-tailed macaque, Poison dart frog

Options

A. Penguin in group I should be interchanged with Caribou in group II.
B. Sloth in group III should be replaced with Eel.
C. Musk ox in group II should be replaced with Lynx whereas Carp in group III should be replaced with Armadillo.
D. White oryx in group IV should be interchanged with Meerkat in group I.

Explanation

To solve the problem of identifying the wrong member in each group categorized by Prashant based on their habitats, we will analyze each group one by one.

### Step 1: Analyze Group I
**Group I: Meerkat, Fennec fox, Camel, Penguin**

- **Meerkat**: Found in desert habitats.
- **Fennec fox**: Also found in desert habitats.
- **Camel**: Found in desert habitats.
- **Penguin**: Found in cold regions (Antarctica, etc.).

**Conclusion**: The wrong member in Group I is **Penguin** because it does not belong to the desert habitat like the other three.

### Step 2: Analyze Group II
**Group II: Polar bear, Musk ox, Blackbuck, Caribou**

- **Polar bear**: Found in the Arctic (Tundra region).
- **Musk ox**: Found in the Arctic (Tundra region).
- **Blackbuck**: Found in grasslands, particularly in India.
- **Caribou**: Found in the Arctic (Tundra region).

**Conclusion**: The wrong member in Group II is **Blackbuck** because it is not from the Tundra region like the other three.

### Step 3: Analyze Group III
**Group III: Carp, Climbing perch, Arowana, Sloth**

- **Carp**: Freshwater fish.
- **Climbing perch**: Freshwater fish.
- **Arowana**: Freshwater fish.
- **Sloth**: Found in rainforests.

**Conclusion**: The wrong member in Group III is **Sloth** because it does not belong to the freshwater habitat like the other three.

### Step 4: Analyze Group IV
**Group IV: White oryx, Toucan, Lion-tailed macaque, Poison dart frog**

- **White oryx**: Found in desert habitats.
- **Toucan**: Found in tropical rainforests.
- **Lion-tailed macaque**: Found in rainforests.
- **Poison dart frog**: Found in rainforests.

**Conclusion**: The wrong member in Group IV is **White oryx** because it is not from the rainforest habitat like the other three.

### Final Summary of Wrong Members
- Group I: **Penguin** (should be a desert animal)
- Group II: **Blackbuck** (should be a Tundra animal)
- Group III: **Sloth** (should be a freshwater fish)
- Group IV: **White oryx** (should be a rainforest animal)
