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. Stereo
B. Transistor
C. Television
D. Radio

Answer

To solve the problem, we need to identify which of the four options does not belong to the same group as the others based on their characteristics. Let's analyze each option step by step.

### Step 1: Identify the options
The options given are:
1. Stereo
2. Transistor
3. Television
4. Radio

### Step 2: Analyze each option
- **Option 1: Stereo** - A stereo is a device that primarily produces sound. It is used for playing music.
- **Option 2: Transistor** - A transistor is an electronic component that can amplify sound. It is often found in devices that produce sound, but it does not produce sound by itself.
- **Option 3: Television** - A television is an audio-visual appliance that produces both sound and video. It is used for watching shows and movies.
- **Option 4: Radio** - A radio is a device that produces sound. It is used for listening to music and news broadcasts.

### Step 3: Group the options based on characteristics
From the analysis:
- Options 1 (Stereo), 2 (Transistor), and 4 (Radio) are primarily associated with sound production.
- Option 3 (Television) is different because it produces both sound and video.

### Step 4: Identify the odd one out
Since options 1, 2, and 4 are all devices that primarily deal with sound, and option 3 (Television) is the only one that produces both sound and video, we conclude that:

**The odd option out is Option 3: Television.**

### Final Answer
The option that does not belong to the group is **Television**.
