解析：
本题选A。
{02}_____ three influenza type A virus subtypes(子类型) have been found in pigs.

A.By far

B.As far as

C.So far

D.Till far

解析：C考查far短语辨析。句意：迄今为止，在猪身上共发现3种A型流感病毒的子类型。by far最----，-------得多，用在形容词和副词后；as/so far as 就---而言，远到------；so far 迄今为止，主句常用现在完成时，分析have been found完成时被动语态可见so far符合句意和语言用法。
本题选C。
