D
Explanation:
- they are uniform in composition meaning that they are the same throughout
for example: salt water (homogeneous) is the same through out you can not physically separate salt water.
A heterogenous mixture such as rocks and water can be physically separated by removing the rocks from the water
- a solution is a special mixture because it is solute dissolved in a solvent... since it is dissolved it is homogeneous
- an alloy is homogeneous because they atom mix during a liquid state that combines them
