Answer

To determine which statements about Cycas are correct, let's analyze the options step by step:

### Step 1: Analyze the first statement
**Statement:** Cycas has characteristics of branched stems and pinnate leaves.

**Analysis:**
- Cycas can have either branched or unbranched stems.
- It is true that Cycas has pinnate leaves, but the statement about branched stems is not universally applicable.

**Conclusion:** This statement is **incorrect**.

### Step 2: Analyze the second statement
**Statement:** Cycas is a dioecious plant.

**Analysis:**
- Dioecious means that male and female reproductive organs are found on separate plants.
- In Cycas, male cones and female structures (megasporophylls) are indeed found on different plants.

**Conclusion:** This statement is **correct**.

### Step 3: Analyze the third statement
**Statement:** Mycorrhizal associations are commonly found in the roots of Cycas.

**Analysis:**
- Cycas roots are known for having coralloid roots, which form a symbiotic relationship with cyanobacteria, not mycorrhizal fungi.
- Therefore, the statement about mycorrhizal associations is incorrect.

**Conclusion:** This statement is **incorrect**.

### Final Conclusion
The only correct statement about Cycas is that it is a dioecious plant. Therefore, the correct answer is **option B**.
