Select the statement that is not equivalent to-- "it is not true that england and africa are both countries." a. if england is a country, then africa is not a country. b. england is not a country and africa is not a country. c. england is not a country or africa is not a country. d. if africa is a country, then england is not a country

The original statement is true only if:

Options a and d are equivalent:

and they both are true in the same cases as above.

Option c is also fine, because it is false only if both England and Africa are both countries, just like the original statement.

Option b, instead, is true only if neither of the two options are countries, so it doesn't cover the cases where only one of the two is a country.
