问题补充：

-- is your phone number? –It’s 84581868.

A. How many

B. What

C. What ‘s

D. How much

答案：

A. How many

(答案→)B. What

C. What ‘s

D. How much

解析：句意:-你的电话号码是什么？-84581868。询问别人的电话号码时应该用What is your telephone number?。how many 提问数量，意思是多少，修饰可数名词；how much 也是来提问数量，修饰不可数名词。不符合句意。在题干中已经有了be动词，故C不对。故选B。
