First you can eliminate D and E because they erased the comma after 'revolution'. There must be a comma there, because 'known as the agrarian revolution' is a dependent phrase.

A -- can't work because 'involving' is present tense and the sentence is talking about a historical event.

C -- 'which involved' does not make sense in this case. 'which' is unnecessary.

So it has to be B.
