Options

A. it's endocarp is cartilaginous
B. it develops from a superior ovary
C. it's actual fruit is located within an edible fleshy thalamus
D. no part of fruit is edible

Answer

To understand why the fruit of an apple is considered a false fruit, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Definition of True and False Fruits**:
- Fruits can be classified into two categories: true fruits and false fruits. True fruits develop solely from the ovary of a flower after fertilization, while false fruits (or accessory fruits) develop from other parts of the flower.

2. **Characteristics of True Fruits**:
- True fruits arise from the ovary after double fertilization. This means that the fruit is formed from the fertilized ovule and contains seeds that develop from the ovary wall.

3. **Understanding False Fruits**:
- False fruits, also known as pseudocarps or accessory fruits, develop from parts of the flower other than the ovary. This can include the thalamus (flower base), peduncle (flower stalk), or other floral structures.

4. **Apple as a False Fruit**:
- In the case of the apple, the fruit is not formed from the ovary alone. Instead, the edible part of the apple is derived from the fleshy thalamus, which surrounds the actual fruit (the ovary). The true fruit, which contains the seeds, is located within this fleshy thalamus.

5. **Conclusion**:
- Therefore, the apple is classified as a false fruit because its edible portion is formed from the thalamus rather than the ovary itself. This is why it is considered a pseudocarp.

### Summary:
The fruit of the apple is said to be false because it develops from the fleshy thalamus rather than solely from the ovary, making it an accessory fruit.
