# Explanation:## Step1: Understanding the Definitions### A homogeneous mixture is one in which the composition is uniform throughout, and the individual components are not visibly distinguishable. A heterogeneous mixture, on the other hand, has a non-uniform composition, and the individual components can be seen and separated physically.## Step2: Analyzing the Options### - **Option A: Saltwater** - Saltwater is a homogeneous mixture because the salt dissolves completely in water, and the individual components are not visible.- **Option B: Oxygen** - Oxygen is a pure substance, not a mixture.- **Option C: Orange juice with pulp** - Orange juice with pulp is a heterogeneous mixture because the pulp can be seen and separated from the liquid.- **Option D: Water with ice** - Water with ice is a heterogeneous mixture because the ice can be seen and separated from the liquid water.# Answer:### A. Saltwater
