three of the following four are alike in a certain way and so form a group. Which is the one that does not belong to that group ?

Options

A. Fish
B. Scorpion
C. Crab
D. Octopus

Answer

To solve the problem of identifying which option does not belong to the group, we can follow these steps:

### Step 1: Identify the Options
We have four options to consider:
1. Fish
2. Scorpion
3. Crab
4. Octopus

### Step 2: Analyze Each Option
- **Fish**: Fish are aquatic animals that live in water and cannot survive outside of it for long.
- **Scorpion**: Scorpions are terrestrial arachnids that can live both in water and on land. They do not require water to survive.
- **Crab**: Crabs are also aquatic creatures that live in water and need it to survive.
- **Octopus**: Octopuses are marine animals that live in water and cannot survive outside of it for extended periods.

### Step 3: Group the Similar Options
From the analysis:
- Fish, Crab, and Octopus are all aquatic animals that depend on water for their survival.
- Scorpion, on the other hand, can survive on land and does not require water to live.

### Step 4: Identify the Odd One Out
Since Fish, Crab, and Octopus all share the characteristic of being aquatic and dependent on water, while Scorpion can live on land and does not need water for survival, we can conclude that:

**The option that does not belong to the group is Scorpion.**

### Final Answer
The correct answer is **Option 2: Scorpion**.
