Answer should be A. As one country can be associated with multiple contacts and one contact can have multiple countries.

Should be A?

Correct answer is: A

For me the correct answer is A: n:n

One contact record could have multiple countries, but not more than one of the same country (1:N) accordingly, each country would also only be associated with a contact once (1:N). If there was N:N that would mean that a contact could be associated with the same country many times and visa versa, but the scenario isn't asking for this. It asks for the countries visited, not the number of times a country is visited. D is correct.

The answer is correct, it's D. A one-to-many relationship doesn't mean that records on the "many" side can be used only once. A many-to-many relationship would also work but isn't necessary because, as someone else said, you don't need to see the Contacts against the Country

If you need to use the country more than once, it has to be a N:N relationship. Otherwise, the country can only be selected once.

Actually they ask only to see which countries a contact been visiting. Not which contacts that visited a country.

Answer should be A
