Answer:
Any of these
Step-by-step explanation:
Adverbs describe the verbs in a sentence, and adjectives describe the nouns in a sentence. Both of those make your sentence better, but they aren't required in order to make a sentence.
Pronouns aren't required either, as it is possible to write a whole sentence just using nouns and no pronouns, even if it would sound weird.
For example: Bob went to the store and Bob bought some carrots, which is Bob's favorite food.
