Understand that the question is asking about a chemical property related to a substance's interaction with fire.
Recall that chemical properties describe how a substance changes or reacts to form new substances, often involving energy changes such as combustion.
Identify that 'flammability' is the chemical property that describes a substance's ability to catch fire and sustain combustion.
Recognize that 'solubility', 'density', and 'malleability' are physical properties, not chemical properties related to fire.
Conclude that the correct chemical property for the ability to catch and sustain fire is 'flammability'.
