Which answer best describes what is happening in the following reaction?

2C8H18 + 25O2 Right arrow. 16CO2 + 18H2O
This is not a redox reaction. It is an example of combustion.
This is a redox reaction in which octane (C8H18) is the reducing agent.
This is a redox reaction in which carbon dioxide (CO2) burns due to ignition.
This is not a redox reaction, because a solution of carbon dioxide and water results.

"This is a redox reaction in which octane (C8H18) is the reducing agent."

Reason: Combustion of octane involves oxidation of C (in C8H18 → CO2, C's oxidation state increases) and reduction of O2 (0 → −2 in H2O and CO2). Octane donates electrons (is oxidized), so it acts as the reducing agent; O2 is the oxidizing agent.
