Neither. C2H2 is a compound (pure substance) so it is not a mixture at all. Hint: mixtures don't have chemical formulas.
Sodium chloride (table salt) is a pure substance because it is a compound made up of sodium and chloride ions in a fixed ratio. It is not a mixture because it cannot be separated into its components by physical means.
Sulfur is not a mixture at all. It is a pure substance. Specifically it is an element.

Cow milk is considered a mixture, not a pure substance. It contains water, fats, proteins, lactose, vitamins, and minerals, all of which are combined but not chemically bonded. The components can vary in concentration and can be separated through physical means, such as centrifugation. Therefore, milk does not have a fixed composition, characteristic of pure substances.
