哪句才對?謝謝!!!!!

對:
C. I play tennis with my friends every Sunday.

C. I play tennis with my friends every Sunday.
係岩....

Easy man, It is gonna be C

the correct answer is :

C. I play tennis with my friends every Sunday.

C. I play tennis with my friends every Sunday. C 是正確

A 錯。因為 every 之後一定是單數，Sundays 是眾數所以錯。

B 錯。every Sunday 之前不用 on。

C 正確。

A is definitely not correct because "every" should be followed by a singluar noun. The correct expression should be "every Sunday". B is also not correct because it is not necessary to use "on" before "every".

C is the correct answer.

I think A. is correct
