Select the correct statement

Options

A. The filaments of the anther in pea plant fuse together to from a single bundle . This is called a monadelphous condition.
B. Generally , dicot seeds are endospermic , but some like castor are non-endospermic
C. When a flower can be divided into two similar halves only in one particular vertical plane , it is actinomorphic
D. In mango and coconut fruit develops from a monocarpellary superior ovary

Answer

To solve the question "Select the correct statement," we will evaluate each provided statement one by one to determine which one is accurate.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- The first statement claims that "the filaments of the anther in pea plant fuse together to form a single bundle and this is called monoadulphous condition."
- In pea plants, the condition is actually diadulphous, where the filaments of the anthers are fused into two bundles, not one. Therefore, this statement is **incorrect**.

2. **Evaluate the Second Statement:**
- The second statement states, "Generally dicot seeds are endospermic but some lycaster are non-endospermic."
- In reality, castor (likely what "lycaster" refers to) is an example of an endospermic seed. Therefore, this statement is also **incorrect**.

3. **Evaluate the Third Statement:**
- The third statement mentions, "When a flower can be divided into two similar halves only in one particular vertical plane, it is called actinomorphic."
- This is incorrect because a flower that can be divided into two similar halves in multiple planes is called actinomorphic. The correct term for a flower that can only be divided in one plane is "zygomorphic." Thus, this statement is **incorrect**.

4. **Evaluate the Fourth Statement:**
- The fourth statement says, "In mango and coconut, fruit develops from the monocarpillary superior ovary."
- This statement is correct. Both mango and coconut fruits develop from a single (monocarpillary) superior ovary. Therefore, this statement is **correct**.

### Final Answer:
The correct statement is: **"In mango and coconut, fruit develops from the monocarpillary superior ovary."**
