(a) Alloys are homogeneous mixtures because they have uniform composition throughout.
Example: Brass is an alloy that shows characteristics of copper and Zinc and their composition varies from 20 to 35 %.
(b) No, a solution can also be solid (alloys) or gaseous (air) also.
(c) No, a solution is always a homogeneous mixture.

[Extra information: A solution is a one-phase mixture that is homogeneous.
A solute is a substance that is dissolved in another substance known as the solvent in such a mixture.
The solvent is the substance that is present in the largest amount.]
