They never mentioned that it must be a smallest 5-digit number.
They only mentioned the smallest number using all 5 cards.
So it must be 1598 (01598).
(The smallest 5-digit even number would be 10598)
Part c is similar.

Hmm … a bit of disagreement over how to interpret the wording.
I believe that when the question says "use ALL the digits …", it should mean the number must contain all 5 digits.
… so answers given by Jibolo should be the correct answers.

Omitting the phrase “5-digit...” will leave some room for confusion for the reader though.
Most other questions of this type will include the “5-digit” phrase. So this particular question, in my opinion, is not optimally phrased.
This is why in exams, a good paper will produce questions which not have ambiguities in the meanings (typical of Cambridge exams for the O and A levels).
