D. Thalamus incompletely covers the ovary

Options

D. A, B only

Answer

To determine which statement is not related to Guava, we will analyze each option one by one based on the characteristics of Guava's flower and fruit morphology.

### Step-by-Step Solution:

1. **Analyze Statement A**: "Floral organs like Sepals, Petals and Stamens are present at the margin of thalamus."
- Guava has an epigynous flower, meaning that the sepals, petals, and stamens are indeed located at the margin of the thalamus. This statement is **true** for Guava.

2. **Analyze Statement B**: "Fruit has stony endocarp."
- The fruit of Guava is a berry, which does not have a stony endocarp. Stony endocarps are characteristic of drupe fruits (like mango and coconut). Therefore, this statement is **false** for Guava.

3. **Analyze Statement C**: "Position of other floral organs with respect to ovary is inferior."
- In an epigynous flower like Guava, the ovary is situated below the other floral organs (sepals, petals, and stamens), which are above it. Thus, this statement is **false** for Guava.

4. **Analyze Statement D**: "Thalamus incompletely covers the ovary."
- In Guava, the thalamus completely covers the ovary, characteristic of epigynous flowers. Therefore, this statement is also **false** for Guava.

### Conclusion:
The statement that is **not related to Guava** is **B**: "Fruit has stony endocarp."
