B. It is a dioecious plant , where male cones and megasporophylls bear on different trees
C. Mycorrhizal associations are commonly found in the roots of Cycas.
D. Both (B) and ( C)

Answer

To determine which statements about Cycas are correct, let's analyze each option step by step.

### Step 1: Analyze the first option
The first option states that Cycas has a "characteristics branched stem and pinnate leaves."
- **Evaluation**: Cycas can have either a branched or unbranched stem. While it is true that Cycas has large pinnate leaves, the statement about the stem being necessarily branched is incorrect.
- **Conclusion**: This option is **wrong**.

### Step 2: Analyze the second option
The second option states that Cycas is a "dioecious plant where male cones and megasporophylls are found on different trees."
- **Evaluation**: This statement is correct. Cycas plants are indeed dioecious, meaning that male and female reproductive structures are found on separate plants. Male cones are produced on male trees, while megasporophylls (female reproductive structures) are found on female trees.
- **Conclusion**: This option is **correct**.

### Step 3: Analyze the third option
The third option states that "mycorrhizal associations are commonly found in the roots of Cycas."
- **Evaluation**: This statement is incorrect. Cycas has coralloid roots that form a symbiotic association with cyanobacteria, not mycorrhizal fungi.
- **Conclusion**: This option is **wrong**.

### Step 4: Analyze the fourth option
The fourth option states "both B and C."
- **Evaluation**: Since option B is correct and option C is wrong, this statement is also incorrect.
- **Conclusion**: This option is **wrong**.

### Final Conclusion
The only correct statement about Cycas is found in option 2. Therefore, the correct answer is option 2.
