Which of the following refers to a homologous graft?

A homologous graft is defined as a transplant involving tissue or an organ taken from a donor of the same species but genetically different from the recipient. This type of graft is termed "allograft" because it typically involves tissues that are not genetically identical, such as human tissues transplanted from one individual to another.

The other terms listed refer to different medical concepts. Dermabrasion is a cosmetic procedure for skin rejuvenation, vitiligo is a skin condition characterized by loss of pigmentation, and pruritus refers to itching. None of these terms relate to the concept of grafting or transplants, making "allograft" the appropriate choice for describing a homologous graft.
