“Which sentence best supports the claim that you can find rare and unusual DVD’s at midtown Home Video”

C.

Explanation:

The sentence that best supports this would be "We also specialize in foreign and art house movies that you may not have heard of". These would be movies that the majority of the customers have not seen or heard of due to the movies being from other countries and because those movies usually do not have large budgets for marketing. Without marketing very few people actually hear about them, this therefore, makes these movies rare and unusual finds.
