The decision made by the author was not completely understandable or comprehensive. So the st blank is questionable

The 2nd blank is limited. The decision made the script limited in its scope or role.

Reductionist is still an adjective. However, reductionist is something that is complicated but explained in a simple manner.

Here we must show that as a consequence of the decision the book does not express all its potential.

So E is wrong

The (i) _______ decision by the author to write the historical novel in the first person has led to a text that is (ii) ________ in view.

We can eliminate omnipotent, and haphazard as well, as there is no choice for the second blank which goes meaningfully with haphazardas a choice for the first blank.

We are left with questionable for the first blank. And since the novel was written from the first person point of view, it definitely must have a limited vision.
