When we speak about a specific place, a specific cinema in this case, the definite article 'the' is used. The noun 'Classic Cinema' is a proper noun, but it is a specific cinema, hence we use 'the' hence option C is correct. 'A' and 'an' are indefinite articles which we use before nouns that are non-specific, the noun here is not any cinema, but a specific one with its name mentioned. Hence options A and B are incorrect. Most proper nouns don't require an article, except for some which are specific, since the 'Classic Cinema' is a specific cinema, option D is incorrect.
