Options

1. A
   The argument is valid; a universal mother follows.
2. B

3. C
   The argument illicitly swaps “for every person there exists a mother” ($\forall$-$\exists$) into “there exists someone who mothers every person” ($\exists$-$\forall$); the witness may depend on the person.
4. D
   The argument is the contrapositive of a true claim.
5. E
   Negating the premise would fix the argument.
