The correct answer is B. Hoarding disorder
Explanation:
Hoarding disorder or compulsive hoarding is a type of mental disorder in which individuals acquire and accumulate large amounts of objects obsessively and are unable to discard any of them. Because of this, in most cases, individuals that suffer from hoarding disorder end up covering most areas of the places where they live with objects which leads to risks in health and other issues that stop them from leading a normal and functional life. This is the type of disorder Graham suffers because it is clear he has begun acquiring and accumulating obsessively car parts, besides this, he is unable to discard the objects he acquires and this has also led to issues in his life because now the objects covered almost all spaces.
