Answer:
C) Analysts can only speak analytically.
Step-by-step explanation:
Nouns are those naming words, or those words denoting or representing names or identities.
Adverbs are those words that modifies, changes the quality or manner of the verbs, adjectives and other adverbs.
In the sentence -
Analysts can only speak analytically.
Analysts is the noun while 'analytically' is the adverb.
They both are from the same word root of 'analysis', with the noun coming before the adverb part of speech. The other sentences either have the adverb coming before the noun or don't contain any same word root noun and adverb or even no noun.
