D. Thalamus incompletely covers the ovary

Options

B. A, B, C, D
C. B alone
D. A and 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 flowers and fruits.

### Step-by-Step Solution:

1. **Option A: Floral organs like Sepals, Petals, and Stamens are present at the margin of thalamus.**
- In Guava, the flower is classified as epigynous, meaning the ovary is inferior, and the other floral organs (sepals, petals, and stamens) are located above the ovary. Therefore, this statement is **incorrect** regarding Guava.

2. **Option B: Fruit has stony endocarp.**
- Guava does not have a stony endocarp. Stony endocarps are characteristic of drupe fruits (like mango and coconut). Guava is classified as a berry, which does not have a stony endocarp. Thus, this statement is also **incorrect** regarding Guava.

3. **Option C: Position of other floral organs with respect to ovary is inferior.**
- This statement is misleading. In Guava, the ovary is inferior, meaning the other floral organs (sepals, petals, and stamens) are above the ovary, not inferior to it. Therefore, this statement is **incorrect** regarding Guava.

4. **Option D: Thalamus incompletely covers the ovary.**
- In the case of Guava, the thalamus completely encloses the ovary since it is an epigynous flower. Thus, this statement is also **incorrect** regarding Guava.

### Conclusion:
All options A, B, C, and D contain incorrect statements about Guava. However, since the question asks for which is not related to Guava, the best choice is **Option A**, as it is the most directly related to the floral structure.

### Final Answer:
**A. Floral organs like Sepals, Petals, and Stamens are present at the margin of thalamus.**
