Solution
The correct option is D Composition is uniform throughout
A mixture is said to be homogeneous if its composition is uniform throughout. For example, air is a homogeneous mixture that contains a number of gases.
The correct answer is D.
Why alternative A is wrong:
If the components of a mixture exist in more than one state then the mixture cannot be homogeneous as the composition will not be constant.
Why alternative B is wrong:
If the composition of a mixture is not uniform throughout, then the mixture cannot be homogeneous.
