The best term to describe 10-karat gold is **B. homogeneous mixture**.
10-karat gold is an alloy made of gold and other metals, and its composition is uniform throughout, making it a homogeneous mixture rather than a pure substance or a compound. A pure substance would be something like 24-karat gold (which is pure gold), while a compound would involve a chemical reaction between substances. A heterogeneous mixture would have distinguishable phases or components that are not uniformly distributed, which is not the case with 10-karat gold.
