Nymphadora Tonks is a Half-Blood witch. Her mother, Andromeda Black (Tonks), was born into the Pure-Blood Black family but was disowned for marrying a Muggle-born wizard, Edward Tonks. With one Pure-Blood and one Muggle-born parent, Tonks is classified as Half-Blood.

Dean Thomas is a Half-Blood wizard. He was raised by his Muggle mother and stepfather, unaware that his biological father was a wizard who was killed by Death Eaters when he refused to join them. This mixed magical and non-magical heritage makes him Half-Blood by blood status.

Rubeus Hagrid is technically Half-Blood, though more accurately Half-Giant. His father was a human wizard, while his mother was a giantess, Fridwulfa. In the Harry Potter blood status classification system, the term Half-Blood typically refers to wizards with mixed magical/Muggle heritage, but Hagrid's case is unique due to his giant ancestry.

Snape's mother Eileen Prince was a witch from a pure-blood family, while his father Tobias Snape was a Muggle. This mixed heritage makes him a Half-Blood wizard, as established in Harry Potter canon.

Dumbledore's mother Kendra was a Muggle-born witch and his father Percival was a pure-blood wizard. While he could be classified as Half-Blood, the Harry Potter fandom and some canon sources suggest he was generally regarded as pure-blood due to his mother's magical ability and status.

Hermione Granger was born to Muggle parents (dentists Mr. and Mrs. Granger) with no magical heritage. Her Muggle-born status was a point of prejudice with pure-blood supremacists like Draco Malfoy who called her 'Mudblood'.

Argus Filch, the caretaker of Hogwarts, was a Squib born to magical parents but unable to use magic. This was a source of great bitterness for him, explaining his hostility toward students and his secret desire to learn magic through Kwikspell courses.

Phineas Nigellus Black was a Headmaster of Hogwarts and Sirius Black's great-great-grandfather. His portrait hangs in Dumbledore's office and Grimmauld Place, and he's known for his disparaging remarks about students and his disdain for Muggle-borns.

Hermione Granger is the correct answer. She is Muggle-born (both parents are non-magical), exceptionally intelligent, and famous for her love of the library - she's often found studying in the Hogwarts Library and is known for reading extensively to solve problems. Rita Skeeter is a journalist, not a student. Griselda Marchbanks is an elderly witch who administered O.W.L. exams. Cho Chang is Ravenclaw Seeker but not Muggle-born.

Before becoming Headmaster of Hogwarts, Albus Dumbledore taught Transfiguration. He was widely considered one of the most powerful wizards of his time and was an expert in this field, having even transformed the school benches into elephants during his practical exam.

Gilderoy Lockhart was appointed as the Defense Against the Dark Arts teacher for the 1992-1993 school year (Harry's second year). He was later exposed as a fraud who used memory charms to steal other wizards' achievements and claim them as his own.

Aurora Sinistra taught Astronomy at Hogwarts. Her classes were held at midnight on the Astronomy Tower, where students observed the night sky and learned about celestial bodies and their movements.

Richard Harris portrayed Professor Dumbledore in the first two Harry Potter films (2001-2002). After his death, the role was taken over by Michael Gambon, not Alan Rickman (who played Snape).

Robbie Coltrane played Rubeus Hagrid in all eight Harry Potter films. His portrayal captured Hagrid's warmth, loyalty, and intimidating size perfectly.
