Answer 1

The correct option is A research

Countable nouns are those nouns which can be counted. Uncountable nouns are usually abstract ideas/ qualities/ physical objects which are not countable due to their form.

Option A: The word "research" is an abstract noun, which is uncountable.

Option B: The word "book" is a concrete noun. It is countable.

Options C: The word "three" is an adjective, not a noun

Option D: The word "gather" is a verb, not a noun.

Hence, the correct answer is Option A.
