The testicular artery typically arises from the abdominal aorta, specifically **below the renal artery**, as it is a branch of the abdominal aorta that supplies the testis. It usually emerges from the posterior abdominal wall, near the level of the renal artery, and courses through the inguinal canal. The renal artery supplies the kidneys, not the testis. The internal iliac and external iliac arteries are involved in pelvic and lower limb supply, not testicular arterial origin. Thus, the correct origin is the abdominal aorta below the renal artery.
**✓ Correct: A. Abdominal aorta below renal artery**
