In A and B, their (plural) is intended to refer to each company (singular).
A plural pronoun cannot serve to refer to a singular antecedent.
Eliminate A and B.

In C, which seems to refer to rival, implying that THE CHIEF RIVAL will determine how efficiently each company can produce computers.
Eliminate C.

more X than Y must serve to compare PARALLEL FORMS.
D: more BY HOW EFFICIENTLY...than ITS VISIONS
Here, by how efficiently (modifier) and its visions (noun phrase) are not parallel forms.
Eliminate D.

In E, more...as is unidiomatic.
Eliminate E.

None of the answer choices is viable.
I would ignore this SC.

In A, can "their" refer to plural antecedent - computers?

Although I am skeptical what "computer vision" will mean - company's vision of computer or computer's vision.
