Choose the word that is opposite in meaning to the given word.
GORGEOUS

a)Desperate
b)Plain
c)Fashionable
d)Sumptuous

Hint: Antonyms are the words that have a contrasting or opposite meaning to the word being talked about.

Complete step-by-step answer:

 Gorgeous means someone who is attractive and good looking. The antonym or the opposite of gorgeous would be a word that means something near: unattractive or uninteresting or ugly.
Desperate has two meanings, of which one is pessimistic and the other is craving for something uncontrollably. This is nowhere near to the opposite of the word Gorgeous, so option a is incorrect.
Plain means something which is simple and simplistic. We can understand and figure out that option b stands nearest to the antonym of gorgeous because Plain it is often referred to as bland and attractive. Hence option b is the correct answer.
Fashionable, as the name is very suggestive, is someone who is an ardent follower of the latest fashion trends and is up to date, so this word in a way can be considered a synonym of gorgeous, and not antonym. So option c is also incorrect.
Option d is Sumptuous, it means something which is opulent and luxurious. It is also the incorrect option as it does not contrast with the meaning of the word in the question.

Note: You do not need to learn a lot of synonyms and antonyms, increasing your vocabulary is the trick here.
