a) A cola drink in a tightly capped bottle.
Work Step by Step
A nice illustration of a homogeneous mixture is a cola beverage in a bottle with a tight cap. The components of homogeneous mixes have the same uniform content throughout the mixture and cannot be seen. Water, sugar, carbon dioxide, and flavorings are just a few of the ingredients that go into making a cola drink. The combination is fully blended and has a consistent appearance. The firmly closed bottle contributes to the consistency of the mixture by preventing gas escape and liquid component evaporation.
The correct answer is (a).
