c. it involves a series of steps, each of which generates a reactive intermediate that brings about the next step

Explanation:

A chain reaction consist of many repeating steps. Chain reaction will never stop until all the reactant has been exhausted. It is more of a cycle of reaction that generate a reactive intermediate that brings about the next step.

Example of a chain reaction is the chlorination of methane.

CH4 + Cl2 ↔ CH3Cl + HCl

CH3Cl + Cl2 ↔ CH2Cl2 + HCl

CH2Cl2 + Cl2 ↔ CHCl3 + HCl

CHCl3 + Cl2 ↔ CCl4 + HCl
