Show answer & explanation
Correct answer: B
A contradiction is a proposition that is always false. This means it evaluates to false under all possible truth assignments.
Tautology refers to a proposition that is always true, so it is not the correct answer.
Contingency is a proposition that can be true or false depending on the input values, so it is not always false.
Therefore, the correct term for a proposition that is always false is contradiction.
