Respuesta :
B is incorrect. It's "That dog amd cat of yours WERE making us laugh that day".
The correct answer is C, 'Are you and Gordon coming to the meeting on Saturday?' It is the only sentence which is correctly written. A should say: 'Aren't your mother....'. B should say: 'That dog and cat of yours were making...' And D: 'Has another topic...'.
So they are all incorrect and contain a mistake, whereas C doesn't have an errr in subject and verb agreement.
