The correct answer is C) Random selection. When evaluating clients' needs and desired results, the following methods are utilized:
- Client consultation: This involves directly discussing with the client their needs and desired results.
- Skin patch test: This is a method used to determine if a person has an allergic reaction to a specific substance by applying patches containing the substance to the skin.
