Correct answer: B
In the Square of Opposition, contrary propositions cannot both be true simultaneously.
Proposition A ('All cows are herbivores') is a Universal Affirmative (A).
Proposition B ('No cows are herbivores') is a Universal Negative (E).
A and E propositions are defined as Contraries. Thus, A and B form the correct contrary pair.
