2. **Analyzing the Options**:
- **Pinus**: Pinus is a gymnosperm known for its wind pollination. The pollen grains produced by Pinus are winged, which aids in their dispersal by wind.
- **Mango**: Mango is a monoecious plant that does not require cross-pollination. Its pollen grains are not winged.
- **Cycas**: Cycas is another gymnosperm, but it does not produce winged pollen grains. It also relies on wind for pollination but has different pollen characteristics.
- **Mustard**: Mustard is primarily pollinated by insects. Its pollen grains are heavy and sticky, which is not conducive to wind dispersal.

3. **Identifying the Correct Answer**: Based on the analysis, the only plant among the options that has winged pollen grains is **Pinus**.
