If one of two contraries is true, then the truth value of the other is

ATrue

BPartially true

CFalse ✓ Correct

DNeither true nor false

Correct answer: (C) False

Explanation

If one of two contraries is true, the other is false.

Contraries cannot both be true at the same time.

So the truth of one immediately rules out the other.

For example, if "All S are P" is true, "No S is P" must be false.

The law of contraries fixes the second as false here.
