Answer

To determine which of the given options is highly inflammable, we need to follow these steps:

1. **Understand Inflammability**: Inflammability refers to how easily a substance can catch fire. A highly inflammable substance ignites quickly and burns easily.

2. **Identify Ignition Temperature**: The ignition temperature is the minimum temperature at which a substance starts to burn. The lower the ignition temperature, the more flammable the substance is.

3. **Compare Options**: We need to compare the ignition temperatures of the substances provided in the options. The substance with the lowest ignition temperature will be the most highly inflammable.

4. **Determine the Most Inflammable Substance**: After comparing the ignition temperatures of the options, we find that kerosene oil has the lowest ignition temperature among the options provided.

5. **Conclusion**: Therefore, the highly inflammable substance among the options is kerosene oil.

### Final Answer:
