Question

what does \politeness\ mean? the state of being polite an act that isnt polite the reason for being polite a person who is polite

Explanation:

The suffix "-ness" is used to form nouns from adjectives, indicating a state or quality. "Polite" is an adjective. So, "politeness" means the state of being polite. The other options: "an act that isn't polite" is the opposite (impoliteness in part); "the reason for being polite" adds an extra element (reason) not in the word's base meaning; "a person who is polite" would be a "polite person" (not the state).

Answer:

the state of being polite
