Which chemical property makes a substance suitable as a fuel? low conductivity low flammability high conductivity high flammability

Option (d) is the correct answer.

Explanation:

A substance which upon burning produces heat, energy or power is known as fuel.

Conductivity is defined as the ability of a substance or solution to conduct electricity. When the substance is able to conduct at a faster rate then it means it has high conductivity.

When a substance is able to conduct electricity slowly then it means it has low conductivity.

Flammability is defined as the ability of a substance to catch fire. When a substance readily catches fire then it is known that it has high flammability. When a substance does not catches fire easily then it is known that the substance has low flammability.

Thus, we can conclude that high flammability is the chemical property which makes a substance suitable as a fuel.
