Não tenho certeza se isso está correto, mas,
Este é um bom dia.
I would say that C. antique is the best answer. Since the Latin root antico means old and antique means something that is old, it is the closest in root because if you separate antique into Latin, the -que ending signifies "and" so it is literally "and old."
Peanuts hope this helps hope i am brainliest i need it
