Which choice contains a noun part of speech followed by an adverb part of speech from the same root word? A) Save the analysis for analysts. B) If you analyze me, I'll analyze you. C) Analysts can only speak analytically. D) Too much analyzing can lead to an analysis of failure.

The answer is option C: Analysts can only speak analytically.

Nouns are words (other than pronouns) that identify or name things, places or people. Adverbs modify adjectives, verbs or other adverbs, and indicate time, place, manner, degree or circumstance.

In sentence C, "Analysts" is a noun and "analytically" is an adverb. The rest of the statements contain nouns and verbs.
