A - Although he denies them, Dr. Vasequez faced several scandals last year.
A complex sentences must have both a dependent clasuse (although he denies them) and an independent clause (Dr. Vasquez faced several scandals last year.
Options B and D are compound sentences (two independent clauses) and option C is a simple sentence.
I have found the choices to your question from another source and I will place them here:
A) All order, I've come to understand, is theoretical, unreal -- a harmless, sensible, smiling mask men slide between the two great, dark realities. B) I seize up a sleeping man, tear at him hungrily, bite through his bone-locks and suck hot, slippery blood.C) Fate often enough will spare a man if his courage holds. (162)D) As if casually, in plain sight of them all, I bit his head off, crunched through the helmet and skull with my teeth and, blood-slippery body in two hands. (79)
Among these choices, the passage that would suggest that "life is meaningless" would be option A. That passage suggests that every order is not real, that people just unknowingly go over between the "two dark realities".
It supports that life is meaningless by telling us that the order we try so much to achieve and maintain is nothing but a theoretical concept - an imagination.
The excerpt from <span>Black Boy that best demonstrates the idea that Wright’s family feels frustrated and trapped in their financial situation is </span><span>C. At night there were long, halting discussions about our going to live with Granny, but nothing came of it. Perhaps there was not enough money for railroad fare.
You can see clearly here that they wanted to send to boy to his grandma so that both them and he could live a little bit better, however, they couldn't manage to set aside even that little money to send him away.
