Answer

To determine which fruits show an edible thalamus, we need to understand the difference between true fruits and false fruits.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **True Fruits**: These fruits develop solely from the ovary of the flower. Only the ovary is the edible part.
- **False Fruits**: These fruits develop from the ovary as well as other floral parts, including the thalamus. In these fruits, the thalamus is also edible.

2. **Analyze the Options**:
- **Option A: Apple, Custard Apple, Guava**:
- Apple is a false fruit (edible thalamus).
- Custard apple is a true fruit (only ovary is edible).
- Guava is also a true fruit.
- **Conclusion**: This option contains only one false fruit (apple) but not all fruits have edible thalamus. **Incorrect**.

- **Option B: Apple, Strawberry, Pear**:
- Apple is a false fruit (edible thalamus).
- Strawberry is also a false fruit (edible thalamus).
- Pear is a false fruit (edible thalamus).
- **Conclusion**: All fruits in this option have an edible thalamus. **Correct**.

- **Option C: Apple, Pineapple, Strawberry**:
- Apple is a false fruit (edible thalamus).
- Pineapple is a true fruit (only ovary is edible).
- Strawberry is a false fruit (edible thalamus).
- **Conclusion**: This option is incorrect because it includes a true fruit (pineapple).

- **Option D: Jackfruit, Guava, Pineapple**:
- Jackfruit is a true fruit (only ovary is edible).
- Guava is a true fruit (only ovary is edible).
- Pineapple is a true fruit (only ovary is edible).
- **Conclusion**: This option is incorrect as all are true fruits.

3. **Final Answer**:
