The correct option is C Countable Noun
Countable nouns refer to nouns that can be counted, they have a singular and plural form like puppy/puppies. The italicized word 'puppies' is hence, a countable noun and option A is correct. Uncountable nouns are nouns that cannot be counted, as they are made up of tiny fragments or particles and are impossible to count. They do not have a plural form, examples are rice, flour and milk. 'Puppies' is the plural form of the singular noun 'puppy', they can be counted, hence option B is incorrect. Abstract nouns refer to an idea, concept or state of being and 'puppies' does not refer to an idea, but they're physical beings, hence option C is incorrect. Collective nouns refer to a group of people, animals or things like crew, swarm, herd; as the noun 'puppies' does not refer to a group of puppies, but it's a plural common noun, hence option D is incorrect.
