What is the antonym (opposite) of the word ‘Robust’?

Explanation

‘Robust’ describes being strong and healthy, or sturdy in construction, so its opposite is ‘frail,’ meaning physically weak or delicate, as in ‘The robust economy of the previous decade gave way to a frail one after the crisis.’ The other three options are all synonyms of ‘robust,’ making ‘frail’ the correct antonym.
