As the number of participants has increased from 60 to 98, we wonder if we can use Lecture Hall ‘A’ as ‘B’ will be too small.
Fewer people will attend the meeting.
Lecture Hall B has been occupied.
The meeting will be held in Lecture Hall A.
根据这句话的前半部分，可以判断选项A与原文的意思不符；文中未提及选项B的内容。从“we wonder if we can use Lecture Hall A”可知“会议将在A报告厅举行”，所以C项正确。
