To determine the answer to the question of what must be supplied for a fuel to burn completely, we need to consider the essentials for combustion.

Combustion is a chemical reaction where a substance combines with an oxidant and releases energy in the form of light and heat. The essential requirements for combustion are:
1. Fuel: A substance that will combust.
2. Heat: An initial spark or source of ignition to start the combustion.
3. Oxidizing agent: Typically oxygen, which reacts with the fuel to produce combustion.

Here are the options provided for the question:

A. Tension - Tension is not relevant to the combustion process.
B. Pressure - While pressure can influence the rate of reaction in combustion, it is not a necessity for the fuel to burn.
C. Oxygen - Oxygen is the key oxidizing agent necessary for combustion to occur.
D. Vapor - Vapor alone cannot sustain combustion without an oxidizing agent.

Hence, the correct answer is:

C. Oxygen

For a fuel to burn completely, a sufficient quantity of oxygen must be supplied.
