Concept:An antonym is a word that means the opposite of another word. ‘Tangible’ means something you can touch or feel physically (concrete). Its opposite will be something that cannot be touched or is abstract.
Explanation:First, understand the meaning of ‘tangible’: it refers to objects that are real and can be perceived by touch (e.g., a rock).
The word ‘intangible’ means not able to be touched – it describes ideas, feelings, or abstract qualities (e.g., love, trust). This is the direct opposite of tangible.
Now check the other options: ‘Invisible’ means cannot be seen, but something invisible can still be tangible (e.g., air). ‘Real’ means existing, which is similar, not opposite. ‘Definite’ means clearly defined, not opposite.
Thus, the correct antonym is ‘intangible’.
Answer:C. Intangible
