Question

Which statement is the Law of Detachment? (1 point)
a.If p q is a true statement and q is true, then p is true.
b.If p q is a true statement and q is true, then q p is true.
c.If p q and q r are true, the p r is a true statement.
d.If p q is a true statement and p is true, then q is true.

Answer 1

I believe that it's d. Since p -> q is a true statement and p is true, q has to be true because t -> t is true, but t -> f is false.
