detailed solution

Correct option is A

A noun is a part of speech in English grammar that names or identifies a person, place, or thing. Adjectives and abstract nouns are frequently confused. Qualities within people, animals, or objects are abstract nouns. Examples include honour, compassion, goodness, and love. Both adjectives and abstract nouns can often be mistaken for each other. It is how we use the words in a sentence that would define whether it is an abstract noun or an adjective. E.g. Meena is a kind woman(here, 'kind' is an adjective since it describes the noun), while Kindness is a virtue (here, it's a noun since it refers to a quality)
