Answer: (A)

Verified step by step guidance

1. Understand that the question is asking for a chemical property related to a substance's ability to burn or ignite in the presence of oxygen.
2. Recall that chemical properties describe how a substance interacts with other substances or changes its chemical identity, such as reacting with oxygen.
3. Identify that 'flammability' is the term used to describe the ability of a substance to catch fire and burn when exposed to oxygen.
4. Recognize that 'density' is a physical property related to mass and volume, 'malleability' refers to the ability to be shaped or hammered, and 'solubility' is about dissolving in a solvent, none of which describe burning.
5. Conclude that the correct term describing the chemical property allowing a substance to burn or ignite in oxygen is 'flammability'.
