These proposals sought to place greater restrictions on the use and copying of digital information than ______ in traditional media.
A．exist
B．exists
C．existing
D．to exist请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：A
解析：than后面省略了成分“those restrictions which”，排除选项B。此处为省略了which的定语从句，排除选项C。exist in存在于，强调的是一个客观存在，所以用一般现在时。因此A项正确。
