Answer:
Complementary antonyms
Step-by-step explanation:
Antonyms generally refers to words that are direct opposite of each other in meaning. Antonyms are of 4 types namely:
- Gradable: when the opposing words can be qualified by adverbs. E.g wet/dry
- Complementary: when the opposing words cannot be graded and can exist independently of each other. E.g true/false
- Converse: when the opposing words are complementary, that is, one cannot exist without the other. E.g husband/wife
- Multiple taxonomies: A group of words that comprise of a fixed system. E.g spring/summer/autumn/winter
The correct choice in this case is therefore complementary.
