因为由题意我们能够猜出出题者的意图是考我关于定语从句的相关知识点.
由此我们可以从后面的“they used to go to have meetings.”,分析其结构.由于“the meeting-room”不能做作后面的宾语或是状语,所以不能使用that,只能使用where
解析：
当表示时间或地点的名词作先行词时,要判断出它们在从句中作状语还是主语或宾语.作状语时用关系副词,反之用关系代词.
关系副词：
1、why
关系副词why主要用于修饰表原因的名词（主要是the reason）,同时它在定语从句中用作原因状语.如：
We don’t know the reason why he didn’t show up.我们不知道他为什么没有来.
She didn’t tell me the reason why she refused the offer.她没跟我讲她拒绝这项工作的原因.
与关系副词when和where不同,why可以换成that或省略.如：
That’s one of the reasons (why,that) I asked you to come.这就是我请你来的原因之一.
另外,与关系副词when和where可以引导非限制性定语从句不一样,why只能引导限制性定语从句,不能引导非限制性定语从句.如：
他失去工作的主要原因是他喝酒.
误：The main reason,why he lost his job,was that he drank.
正：The main reason why he lost his job was that he drank.(同位语从句)
2、when
关系副词when主要用于修饰表时间的名词,同时它在定语从句中用作时间状语.如：
There comes a time when you have to make a choice.你必须作出抉择的时候到了.
Gone are the days when they could do what they liked.他们为所欲为的日子一去不复返了.
We’ll put off the picnic until next week,when the weather may be better.我们将把野餐推迟到下星期,那时天气可能会好一点.
注意不要一见到先行词为时间名词,就以为一定要用关系副词when来引导定语从句,同时还要看它在定语从句中充当什么成分——如果在定语从句中用作时间状语,就用when；如果在定语从句中不是用作时间状语,而是用作主语或宾语,那就不能用when,而要用that,which等.如：
Don’t forget the time (that,which) I’ve told you.不要忘记我告诉你的时间.
关系代词that / which在定语从句中用作动词told的宾语,正因为是用作宾语,所以也可以省略.
3、where
关系副词where主要用于修饰表地点的名词,同时它在定语从句中用作地点状语.如：
This is the village where he was born.这就是他出生的村子.
That’s the hotel where we were staying last summer.这就是我们去年夏天住的旅馆.
Barbary was working in Aubury,where she went daily in a bus.巴巴拉在奥伯里工作,每天得坐公共汽车去上班.
与前面when的情况一样,注意不要一见到先行词为地点名词,就以为一定要用关系副词where来引导定语从句,同时还要看它在定语从句中充当什么成分——如果在定语从句中用作地点状语,就用where；如果在定语从句中不是用作地点状语,而是用作主语或宾语,那就不能用where,而要用that,which等.如：
He works in a factory that [which] makes TV sets.他在一家电视机厂工作.

选C.
D.应该是at the meeting room
