The general symbolic proof below is an illustration of what type of proof? Given: w is true
Prove: w → x is true

Assume that ~x is true. Then, ~x → y, and y → z. Since z → ~w, ~x → ~w must be true by the law of syllogism. Therefore, w → x is true.

A.
proof by contradiction
B.
proof by direct reasoning
C.
proof by law of syllogism
D.
proof by contraposition
