The correct answer is option  A) The host’s body could reject the transplanted stem cells.

Although the stem cells which are used to regenerate a particular organ are isolated from the bone marrow or adipose tissue of the patient itself, it still has the chances of rejection by the patient's body. This is known as graft rejection. Graft rejection occurs because the host's immune system considers the transplanted organ as foreign tissue and therefore, causes internal bleeding and tissue lysis. In such cases, immunosuppressants like glucocorticoids and corticosteroids are given to suppress the immune response. But, these drugs can cause many side effects to the host's body.
