Answer:
D. Heterogeneous mixtures
Explanation:
An egg (raw egg) is naturally made up of the egg white and the egg yolk. It is a heterogenous mixture because you can separate the egg white from the egg yolk. This is commonly done in baking. Its composition is non-uniform.
It becomes a "homogenous mixture" once you beat the egg. In this situation, you won't be able to separate the egg white from the egg yolk anymore.
