Answer & Solution
Solution:
"Perfunctory" means (of an action or gesture) carried out with a minimum of effort or reflection; done carelessly or merely as a duty. It suggests a lack of genuine interest or depth. The correct antonym is "Thorough," which means performed or executed with great attention to detail; complete and painstaking.
