CO₂ and H₂

C and H₂

All of these

The Fischer-Tropsch synthesis involves the combination of CO and H₂ to form alkanes.

CO (carbon monoxide) and H₂ (hydrogen): are collectively known as "syngas".

The Fischer-Tropsch process uses a catalyst to convert this syngas into liquid hydrocarbons, primarily alkanes.
