The statement p → q represents "if a number is doubled, the result is even.” which represents the inverse?

a-~p → ~q where p = a number is doubled and q = the result is even

b-q → p where p = a number is doubled and q = the result is even

c-~p → ~q where p = the result is even and q = a number is doubled

d-q → p where p = the result is even and q = a number is doubled
