What type of flaw would this be?
Is it mistaking a temporal relationship as being a conditional one? Thanks in advance!!

Is this how i make a thread? By posting a reply to my own post?

For this one, i debated between a and d. But why would a not be an answer?
Thanks in advance.

I see the flawed logic for this one and also see that C is the correct answer but can someone explain to me why B is incorrect? I don't clearly see why b is incorrect.
Thnks in advance!

If you would simply diagram the conditional statements in the stimulus, you would see that the flaw here is an illegal negation of the sufficient and necessary conditions. Here's how I diagrammed it:

-public access --> bay polluted
public access --> -bay polluted

The correct answer choice will be one that improperly negates the terms in a conditional statement. (C) does just that:

violent criminals in solitary --> prison violence increases
-violent criminals in solitary --> -prison violence increases
