Answer is option B i.e."Internal iliac vein"
The internal iliac vein drains blood from the visceral organs in the pelvic region. The internal iliac vein may double all these veins and tributaries join together to form the inferior vena cava.

An enema is administered before surgery to clear the bowel, which helps prevent bowel blockage or contamination during the procedure and recovery period.

In a standard kidney transplant, the donor kidney is placed in the iliac fossa, which is located in the lower abdomen, rather than in the original anatomical position of the kidneys.

Isograft is a tissue or organ transplanted from a donor to a recipient who are identical or monozygotic twins. In an isograft transplantation the chances of rejection are near to nil with identical MHCs as they are genetically identical.

The Major Histocompatibility Complex (MHC) molecules are the cell-surface proteins encoded by HLA genes that are primarily responsible for the immune system recognizing the donor organ as foreign.

Monkey and humans have evolved into two distinct lineages and are distinct species and therefore have a dissimilar genetic composition. Any transplant between these two organisms is known as a xenograft. Which may be rejected vigorously due to greater than required MHC incompatibility.

Allograft is a tissue or organ transplanted from a donor to recipient of the same species but is genetically different and therefore may face rejection during kidney transplant due to distinct HLA proteins

A xenograft involves transplanting tissue between different species, which results in the highest level of genetic variation and the most severe immune rejection response compared to autografts or allografts.
