The correct answer is "B: The White Towel".
The Annunciation Triptych is painting created by Netherlandish artist Robert Campin in 1428. It depicts 3 scenarios, "Donors praying in the garden", "The Annunciation of Mary" and "Saint Joseph".
The white towel on Virgin Mary's hands represents her virginity and purity, which is one of the main religious symbols of Roman Catholicism.
