B) Dementors sucked out Ron and Hermione's souls

Explanation:

In the book titled Harry Potter and the Cursed Child at Act Three, Scene 1-11 it was revealed that after Hermione blocked Albus's spell, the Dementors were after the group of Hermione, Scorpio, Ron, and Snape.

However, Hermione believed the Dementors were only after her, so she wished to sacrifice herself for the safety of others. Before she does that, she declared her love for Ron. In return Ron also decided to stay instead of running, he prefers both of them to be killed together instead.

Therefore both Hermione and Ron stayed behind and "Dementors sucked out Ron and Hermione's souls."
