Given the statement "If Jack’s pet is a pig, then Jack’s pet cannot fly,” which statement represents the converse?

q → p, where p = Jack’s pet is a pig and q = Jack’s pet cannot fly
~q → ~p, where p = Jack’s pet cannot fly and q = Jack’s pet is a pig
p → q, where p = Jack’s pet is a pig and q = Jack’s pet cannot fly
q → p, where p = Jack’s pet is not a pig and q = Jack’s pet is a pig
