If \(a\le b\) and \(b<c\), which of the following conclusions is always correct?

Answer and explanation

Correct answer: \(a<c\)

By the transitive property of inequalities, \(a\le b\) and \(b<c\) imply \(a<c\). Even when \(a=b\), we have \(a=b<c\), so the final inequality remains strict. Equality in option B is not necessary, while options C and D contradict the given chain. Exam tip: in a chain of mixed inequalities, one strict comparison is enough to make the comparison between the outer terms strict.
