Is an example of a homogeneous mixture Na-OH solution Mortar (mixture of water sand and cement) Vinegar and oil salad dressing more than one response is correct?

A homogeneous mixture is one where the components are uniformly distributed, and you cannot distinguish them visually. Among the options provided, a NaOH solution and vinegar are homogeneous mixtures, as they consist of dissolved substances that appear uniform. Mortar, which consists of sand, water, and cement, is a heterogeneous mixture because its components remain distinct. Oil and vinegar salad dressing is also heterogeneous since the oil and vinegar separate into layers.
