Explanation:

First Question (What is made up of solutes and solvents?)

A solution is defined as a homogeneous mixture composed of a solute (the substance being dissolved) and a solvent (the substance doing the dissolving). A suspension is a heterogeneous mixture with particles that settle, and a colloid is a heterogeneous mixture with dispersed particles that don't settle but aren't dissolved like in a solution.

Concentration of a solution is related to the amount of solute relative to the solvent. Adding more solute (while keeping the solvent amount constant or increasing it less) increases the concentration. Adding water (a solvent) or more solvent would dilute the solution, decreasing its concentration.

Answer:

B. Solutions (assuming the options are labeled as A. Suspension, B. Solutions, C. Colloid)
