Final answer:
The statement is grammatically incorrect, as the incorrect verb form is used with a plural subject.
Step-by-step explanation:
The statement "Papa et maman aiment jouer aux échecs le dimanche" is INCORRECT grammatically.
In this sentence, the subject "Papa et maman" is plural, so the correct verb form should be "aiment." However, the verb form used here is the singular form "aime."
The correct grammatical form of this sentence would be "Papa et maman aiment jouer aux échecs le dimanche."
