A
Correct answer
Explanation
Severus Snape was indeed a Death Eater, branded with the Dark Mark on his left arm. He joined Voldemort's ranks after leaving Hogwarts but became a double agent for Dumbledore after Voldemort threatened Lily Potter's life. Snape's Death Eater status was real, making his position as a spy even more dangerous and pivotal to Dumbledore's plans against Voldemort.
