The correct answer is B. It releases energy that is used for power.

The combustion of hydrocarbons is primarily important because it releases energy, which is harnessed for various purposes, including electricity generation, powering vehicles, and fueling industrial processes. While water is a byproduct of combustion, it is not the main reason for its importance to modern society. Combustion does not release light in a practical sense for seeing at night, and it does not release oxygen for breathing.
