Answer:
B. Noun. A noun is a person, place, thing, or idea. Oddities and activities are things/ideas.
Explanation:
Most adverbs typically end in -LY. 'Activities' and 'oddities' are not verbs, or actions. Adding the suffix -ity will change the word's part of speech, so it won't remain an adjective. Oddities and activities are things or ideas (nouns such as ideas can be concrete or abstract, like 'oddity.')
