Answer:
Common noun
Explanation:
Common nouns are nouns that name a class of person, place, thing, animal or event in a general way (they do not refer to someone or something in specific as proper nouns do), and that are not to be capitalized unless they begin a sentence or are part of a title. The term report, then, is a common noun because it refers to a class of thing or of piece of information, and is not to be capitalized.
