What is true for Cycas?

Options

A. (a) Cycas is dioecious
B. (b) Ovules without integument
C. (c) Largest female cone
D. (d) of the above.

Answer

### Step-by-Step Solution:

1. **Identify the Organism**: The question asks about Cycas, which is commonly known as sago palm and belongs to the group of gymnosperms.

2. **Evaluate Statement A**: The first statement claims that Cycas is dioecious. This means that male and female reproductive structures are found on separate plants. This statement is true because Cycas has distinct male and female cones that are produced on different individuals.

3. **Evaluate Statement B**: The second statement suggests that Cycas ovules are without integument. This statement is false. In fact, Cycas ovules have one integument, which is a protective layer surrounding the ovule.

4. **Evaluate Statement C**: The third statement claims that Cycas has the largest female cone. This statement is also false. While Cycas does have large ovules in its female cones, it does not possess the largest female cone compared to other gymnosperms.

5. **Conclusion**: After evaluating all statements, the only true statement about Cycas is that it is dioecious (Statement A). Therefore, the correct answer is option A.
