Answer:Angry and defeated, he began spreading malicious lies about his opponent
Explanation:Maliciousness is an adjective that essentially mens “evil.” Thus, the answer cannot be “We will meet, discuss the malicious…” because this is using malicious as a noun. It cannot be “Be careful not to malicious when you are talking…” because this is using malicious as a verb. It cannot be “The chef served a malicious meal…” because while this sentence uses malicious as an adjective, it is not using it with the correct meaning.
