选A,因为这里的open是当形容词来用的,意思是“公开的,开放的”.不是做动词用,所以不选C.
请及时采纳,多谢!

that引导定语从句 指代先行词workshops 在定语从句中做主语
be open to对....开放 这里open作形容词 对...开放的,开业的
open作为动词时打开的意思 开门,开窗户,打开盒子等,所以不能选C

be open to是固定搭配
对…开放;愿接受…的
eg:School playgrounds will be open to the public.
学校的游乐场也将对公众开放。
有不明白的地方再问哟,祝你学习进步,更上一层楼! (*^__^*)

C是过去式,Were也是过去式,所以不能悬C
