This answer choice is a fragment. There is no independent clause. "involving" needs to be changed to "involved" so that we have a working verb.
Incomplete Sentence.

Correct. Our subject is "revolution." Our working verb is "involved." We have a parallel structure, although it is pretty messy, mostly because we have two different verbs "introduction" and "substitution."
"...introduction
of fields and
of techniques and crops, and the
substitution of commercial for farming.
The construction is basically this, "...
the introduction of X
and of Y and Z, and
the substitution of A for B."

Incomplete Sentence.

Also, our subject verb construction doesn't make much sense. "widespread changes, known as the agrarian
revolution involved the introduction of..."
The "known as" construction is
introducing our subject,
revolution. Immediately after the subject, without a comma, we get the verb
involved. This isn't grammatically correct. We need a comma after the "known as" construction.

This one is a hot mess. Incorrect usage of "that." As well as an unparallel construction.
