Hi ,
There's a clear split here abc and de
de is incorrect because which can't refer back to the act of typing(basically any verb since it's a pronoun and must refer back only to a noun non ambiguously)
Here which refers to digital typesetting.
A is wrong as we don't know what it refers to.
B makes it clear that Manuscripts had to be typset
C suggests that the typographers developed digital typesetting hence wrong.
