Answer: (D) can accept grafts from each other (both (A) and (B))
Dizygotic twins, also known as fraternal twins, do not have identical MHC haplotypes or T cells. However, they can sometimes accept grafts from each other due to shared placenta and similar immune environments, but they still have distinct immune systems.
