Antonyms — Choose the option that is most nearly opposite in meaning to ‘‘BASE’’ (English vocabulary: foundation vs. apex; word-meaning question for competitive exams).

Given data

• Word asked: BASE
• Options: Climax; Height; Top; Roof

Concept/Approach
‘‘Base’’ typically denotes the bottom, foundation, or lowest supporting part.Its direct antonym in spatial orientation is the uppermost point, i.e., ‘‘top’’ or ‘‘apex’’.

Step-by-step reasoning
Identify semantic axis: bottom ↔ top.Among the options, ‘‘Top’’ is the precise general antonym to ‘‘Base’’.‘‘Climax’’ and ‘‘Height’’ can be figurative peaks but are not the standard lexical opposite used in geometry/structures.‘‘Roof’’ is the top of a building only (domain-specific), not the generic antonym across contexts.

Verification/Alternative
Collocation check: base–top, base–apex are conventional antonymic pairs in mathematics and everyday usage.

Common pitfalls
Choosing ‘‘Roof’’ due to building imagery; however, antonym needs to be domain-neutral.
