--Do you like eating appies or pears?----I DON'T mind.

选B两者都用both,either两者中任何一个,这两个词都可充当主语、谓语、定语和同位语.以下是列子：
1.做主语：Both are right.= Both of the answers are right.这两个答案都对.
Either(of them)is OK.(他们两个中)任何一个都行.
2.作宾语,可单独使用,也可以与of连用,放在动词或介词之后.例如：
I don't know which book is the better；I shall read both.我不知道这两本书哪一本好,所以我两本都读.
3.作定语,both后面接复数名词,either和neither后面接单数名词.例如：
Both answers are right.两个答案都对.
On either side of the river there are a lot of trees.河的两边都有许多树.
4.both作主语的同位语,一般放在实义动词前,系动词be、情态动词、助动词后；作宾语的同位语,直接放在其后(either做同位语的情况较少).例如：
You must both come over this evening.你们俩今晚必须都过来一趟.(作主语you的同位语)
We are both from Chongqing.我们两个都来自重庆.(作主语we的同位语)
He helped us both.他帮助了我们两个人.(作宾语us的同位语)
