Final answer:
The correct sentence using the underlined word 'effect' properly is D. 'Effect' as a verb is used to indicate causing something to happen, which is appropriate for the context of lobbyists causing changes in policy.
Step-by-step explanation:
The sentence where the underlined word is used correctly is: The lobbyists were able to effect radical changes in the economic policy. In this sentence, 'effect' is used properly as a verb meaning 'to bring about' or 'to cause to happen'. The other sentences use words incorrectly: 'insight' instead of 'incite' in sentences A and B, and 'affect' instead of 'effect' in sentence C.
