TheHistorian:
Another very tricky question that needs a cautious approach else an inevitable fallibility.
Let's take a cursory look at the structural composition of the sentence the question is extracted from.
He looked.......everyone in authority as an enemy.
Taking a keen observation,The "LOOKED" in this above sentence does not connote "VISUALISATION" like most people will hurriedly conclude.
An example is;
I LOOK AT Fatima's beautiful face every morning.
The "look at" here is a verbal phrase that performs the function of VISUALIZATION.
Unlike;;
We LOOK ON Bola as the authority on the matter.
The "look on" here is a verbal phrase that performs the function of PERCEPTION i.e what you consider/perceive people to be.
Back to the question;
He looked.......everyone in authority as an enemy.
You will agree with me that the correct answer is option A= looked ON.
Meaning He considers/perceives everyone who is in a position of authority as a foe.

Thanks for the job well done @the historian ,you indeed decoded the context and made it more clear to the hurried dudes .However ,I knew it well you might've forgot that "LOOK ON" and "LOOK AT" are both phrasal verbs not verbal phrase .Besides verbal phrases are the combination of two or more verbs e.g should have , will have been , must have been , and so forth.
