Answer: b. The Effect of Gideon v. Wainwright
Step-by-step explanation:
As a result of the case, Gideon v. Wainwright, states became required to provide defendants with attorneys if they could not afford one on their own. The Supreme Court argued that it was necessary in order for the Sixth Amendment - which guarantees defendants a speedy and fair trial - not to be violated.
In the picture described, the attorney has been assigned to the defendant in question so this is indeed the effect of Gideon v. Wainwright.
