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

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding True and False Fruits:**
- A true fruit develops from the fertilized ovary of a flower, containing seeds formed from ovules.
- A false fruit (or accessory fruit) is formed from other parts of the plant, such as the receptacle, in addition to the ovary.

2. **Analyzing the Options:**
- **Cashew:** The cashew nut is the seed, and the cashew fruit (the cashew apple) is considered a false fruit because it develops from the receptacle.
- **Strawberry:** The strawberry is also a false fruit. It develops from an aggregate of achenes, and the edible part is the thalamus.
- **Apple:** The apple is another example of a false fruit. It develops from a ripened thalamus and contains seeds within the core.
- **Maize:** Maize (corn) is a true fruit. The maize grain is a ripened ovary, and the pericarp (the outer layer of the fruit) is fused with the seed coat.

3. **Identifying the Odd One Out:**
- Cashew, strawberry, and apple are all classified as false fruits.
- Maize is the only true fruit among the options.

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