问题解答:

我来补答
A选项的意思是‘’众所周知‘’,但‘’it is known to all that‘’不能作为一个独立的句子,后面要加上所说明的内容,例如:It is known to all that we should conserve natural resources.(众所周知我们应该保护自然资源.)
B选项的意思是‘’这是众所周知的‘’,但which is known to all必须放在所说明的对象的后面,例如:All matter has mass, which is known to all.(一切物质都有质量,这是众所周知的.)
C选项的意思是‘’我们都知道‘’,能单独作为一个句子,但时态不正确,应把‘’knew‘’改为‘’know‘’.
D选项的意思是‘’人所共知;众所周知‘’,as is known to all 只可以用在句首或句尾,用“,”隔开.而as it is known to all不仅可以放在句首,还可以后面加“that”从句.
,例如:As  it is known to all china is a great country.(众所周知,中国是一个伟大的国家.)

因此答案选D,如有疑问请继续追问.
