oxygen, this is because it lighter than air hence diffuses faster.Air is a mixture hence consists of variety of gases,making it heavier therefore it diffuses slower than oxygen.

Oxygen is diffuses faster because the diffusion of gases is a unique property of them as the gaseous particles have high kinetic energy therefore they exhibit the random motion and move easily.
The movement of gas from high pressure to low pressure is called as diffusion. It depends on the molar mass of gas. Here oxygen gas has less molar mass compare to air, therefore, it will diffuse faster compared to air.
As the molar mass increases, the rate of diffusion also decreases.
