Explanation
In the folkstale titled "Harry Potter," Dobby is indeed portrayed as an elf. This can be seen throughout the story, as Dobby exhibits typical elf characteristics such as being small in stature, having pointy ears, and possessing magical abilities. Additionally, Dobby's role in the story aligns with traditional depictions of elves, as he is shown to be helpful and loyal to the main characters. Therefore, the statement "Dobby in the folkstale titled 'Harry Potter' is also an elf" is correct.

Explanation
Dobby is the correct answer because he is the most loved House-elf by Harry in the book "Harry Potter". Throughout the series, Harry forms a strong bond with Dobby, who is fiercely loyal and always looks out for Harry's best interests. Dobby sacrifices himself to save Harry and his friends, further solidifying his place as the most loved House-elf. Kreacher is also a House-elf in the series, but he is not as beloved by Harry as Dobby. Therefore, the correct answer is Dobby.

Explanation
Dobby is a free elf because he was given a sock by Harry Potter, which granted him his freedom from the Malfoy family. Kreacher is not a free elf because he remained loyal to the Black family until the end. Dubblin is not a character from the Harry Potter series, so it cannot be determined if he is a free elf or not. Therefore, the correct answer is Dobby.

Explanation
Toby Jones voiced Dobby in the Harry Potter movie.
