I would say the correct answer is A. Canadian culture encourages people to retain their traditional identity rather than trying to blend into one single culture. The concept of melting pot refers to the U.S. and their immigrational policies that require from immigrants to gain a new national and cultural identity - that of Americans - no matter where they come from and who they are. On the contrary, Canada claims that different cultural identities and diversity add to the country's cultural richness, and the more immigrants retain their original identities, the better the country will be for all of them.
