—Yes. It          by more and more people around the world.

A. accept    B. accepted    C. is accepted    D. was accepted

Answer

C

【解析】

句意：--你知道有1,000,000,000人在使用微信吗？--是的，它被世界上越来越多的人所接受。根据Do you know that 1,000,000,000 people are using WeChat?的谓语动词可知，这里叙述的是现在的事情，所以答语也应该用一般现在时，it指WeChat, 与accept之间是被动关系，所以应该用一般现在时的被动语态，其谓语动词的形式是：am/is/are+done,故选C。
