Yes, you're correct. You can visualize this via a Venn diagram. Let $L$ be the set of all lawyers, let $E$ be the set of all extroverts, and let $W$ be the set of all wisemen. Then the first premise states that $L$ is a subset of $E$ (i.e.: $L$ is contained in $E$), and the second premise states that $E$ and $W$ overlap (i.e.: there is at least one person who is both an extrovert and a wiseman).
Conclusion (a) could be false, since $L$ doesn't need to be contained in $W$ (i.e.: there could be some person who is a lawyer but not a wiseman). You can reason similarly for the other two wrong conclusions.
