In Western-8859-1 encoding, the question is:
Which statement is logically equivalent to ~a → b?
a → ~b
b → ~a
~b → a
~b → ~a
~b → a is the correct answer.
Consider the statement
a=I ate
b=I am hungry
So
~a → b means
If I did not eat, I am hungry.
Try to interpret the rest of the statements, and the only one that is logically equivalent is
If I am not hungry, I ate. (~b→a)
