Choose the word which is closest to the opposite in meaning to the italicized word.
 Everything about him proclaims his effeminacy.
(A) boorishness
(B) manliness
(C) aggressiveness
(D) attractiveness

Hint:Opposites are words lying in an inherently incompatible binary relationship. For example, something that is long entails that it is not short. It is referred to as a 'binary' relationship because there are two members in a set of opposites.

Complete answer:
Effeminacy implies having qualities, preferences, behaviours, etc. (of a man or boy), historically considered feminine, as softness or delicacy. The opposite of effeminacy, as power or courage, is manliness, or possessing attributes typically ascribed to men. Hence, Option B is correct. Boorishness means uncouth in ways or appearance, aggressiveness means hostile or violent behaviour, beauty means the quality of being pleasing or appealing to the senses, among the rest of the choices. These alternatives do not communicate this antonym, and are thus incorrect.

Additional information:
A word that communicates a meaning opposite to another word's meaning, in which case the two words are antonyms of one another. Synonyms: antonym, reverse Antonym: synonym, word equivalent. In relation to that context, two terms which can be interchanged in a context are said to be synonymous.
An antonym is a word meaning the opposite of a different word. "For example, the antonym of" hot "may be" cold. "The root words for the word" antonym "are the words" anti, "meaning" against, "or" opposite, "and" onym, "meaning" name.
Let's take a look at what the term 'synonym' means in order to better understand antonyms. A synonym is a term which has a meaning identical to or exactly the same as another term. Exactly the same are synonyms and antonyms.

Hence the correct answer is option ‘B’.

Note:Antonyms are used to reverse the meaning of a sentence. The use of antonyms is considered very important in English grammar. For correct use of antonyms, you will have to strengthen your vocabulary and memorize synonyms of maximum words.
