A
Correct answer
Explanation
This statement appears in Harry Potter and the Order of the Phoenix. While Voldemort has extensive dark magical knowledge, the statement contextually refers to Dumbledore's superior overall magical wisdom and experience across all branches of magic. However, if taken literally about dark magic specifically, Voldemort could be argued as more knowledgeable.
