Mark the odd one (w.r.t. false fruit)

Options

A. Cashew
B. Strawberry
C. Apple
D. Maize

Answer

To solve the question of identifying the odd one out with respect to false fruits, we need to understand the definitions of true fruits and false fruits and analyze the given options accordingly.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **True Fruit**: A true fruit develops from a fertilized ovary. It contains seeds that have developed from fertilized ovules.
- **False Fruit**: A false fruit (or accessory fruit) is formed from parts of the plant other than the ovary, often including the receptacle or thalamus. It may contain a fertilized ovary but is primarily made from other plant parts.

2. **Analyze the Options**:
- **Apple**: An apple is formed mainly from the thalamus (receptacle) and is considered a false fruit.
- **Strawberry**: A strawberry is made from an aggregate of achenes and the edible part is derived from the thalamus, making it a false fruit.
- **Cashew**: The cashew fruit is also considered a false fruit because the edible part is derived from the receptacle, while the seed (the cashew nut) is the true fruit.
- **Maize**: Maize (corn) develops from a fertilized ovary and contains seeds that have developed from ovules, making it a true fruit.

3. **Identify the Odd One Out**:
- Among the options, apple, strawberry, and cashew are all classified as false fruits because they are primarily formed from parts other than the ovary. In contrast, maize is a true fruit as it develops from a fertilized ovary.

4. **Conclusion**:
- The odd one out with respect to false fruits is **maize**.

### Final Answer:
**Option 4: Maize**
