Answer:
Antonyms are:
c. A word that means the opposite of subsidy.
Step-by-step explanation:
We say two words are antonyms when their meanings are the opposite of each other. Examples of antonyms are good - bad, night - day, hot - cold, among others.
"Subsidy" refers to a sum of money given by the government to producers or businesses in order to help them. Antonyms for subsidy would be: hindrance, blockage, interruption, setback, among others.
With that in mind, we can easily choose letter C as the best option: a word that means the opposite of subsidy.
