Select the antonym of the given word.

Notorious

Popular

The antonym of the word notorious is popular.

Option 1: Efficient The word "efficient" means achieving maximum productivity with minimum wasted effort or resources. It is not directly opposite to "notorious" in terms of meaning. While "notorious" implies having a negative reputation, "efficient" refers to effectiveness and productivity.

Option 2: Popular The word "popular" describes something or someone that is widely liked, admired, or well-accepted by many people. While "notorious" implies having a negative reputation, "popular" does not inherently have a negative connotation. Therefore, "popular" is not the direct antonym of "notorious."

Option 3: Optimistic "Optimistic" refers to having a positive outlook, expecting favorable outcomes, or believing in the best possible result. It is not the direct opposite of "notorious," which pertains to having a widely known negative reputation. Thus, "optimistic" is not the correct antonym of "notorious."

Option 4: Infamous The word "infamous" is indeed the correct antonym for "notorious." Both words describe having a well-known reputation, but while "notorious" refers to having a widely known negative reputation, "infamous" specifically denotes having a widely known reputation for negative or evil actions.
