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. Stick
B. Needle
C. Thorn
D. Pin

Answer

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

### Step 1: List the Options
We have four options:
1. Stick
2. Needle
3. Thorn
4. Pin

### Step 2: Analyze Each Option
- **Stick**: A stick is generally a straight piece of wood or similar material. Both ends of a stick are usually rough and not pointed.

- **Needle**: A needle is a thin, pointed tool used for sewing. It has a sharp point on one end.

- **Thorn**: A thorn is a sharp, pointed structure found on some plants. It also has a sharp point.

- **Pin**: A pin is a small, slender object with a sharp point at one end, used for fastening things together.

### Step 3: Identify Common Characteristics
Now, we can see that:
- The **Needle**, **Thorn**, and **Pin** all have one end that is sharp and pointed.
- The **Stick**, on the other hand, does not have a sharp or pointed end; both ends are rough.

### Step 4: Determine the Odd One Out
Since the Needle, Thorn, and Pin share the characteristic of having a sharp point, while the Stick does not, we can conclude that the Stick is the odd one out.

### Conclusion
The option that does not belong to the group is **Option 1: Stick**.
