18. Choose the word pair below that represents antonyms.

Answer: A

Explanation:

Benevolent and Malevolent are antonyms.

The word pair "Benevolent-Malevolent" represents two opposing meanings, where "benevolent" refers to being kind and generous, while "malevolent" indicates a desire to harm or cause suffering.

A) Benevolent-Malevolent

This option is correct as it directly contrasts two words with opposite meanings. "Benevolent" describes a disposition to do good, whereas "malevolent" implies a wish to do evil, making them clear antonyms.

B) Malevolent-Malignant

While "malevolent" and "malignant" may seem related, they are not true antonyms. "Malevolent" refers to having harmful intent, while "malignant" generally pertains to something that is harmful or invasive, especially in a medical context, but does not imply a direct opposite.

C) Monopoly-Monarchy

This pair does not represent antonyms. "Monopoly" refers to exclusive control over a commodity or service, while "monarchy" is a form of government led by a king or queen. These terms describe different concepts rather than opposing ideas.

D) Monotony-Benevolent

This option is incorrect as "monotony" refers to a lack of variety and is not related in meaning to "benevolent." There is no contrasting relationship between these words, as they pertain to entirely different contexts.

Conclusion

The word pair "Benevolent-Malevolent" is definitively the correct answer as it embodies a direct opposition in meaning, showcasing a clear antonym relationship. All other options fail to present true antonyms, either relating to different concepts or lacking the contrasting nature required to fit the definition of antonyms.
