The correct option is
C Passing out urine.
Urination is the release of urine from the urinary bladder through the urethra to the outside of the body. It is also known medically as micturition. Micturition
occurs when the bladder neck and the external urinary sphincter relax and the bladder contracts, allowing for the unobstructed expulsion of urine.
Thus the correct answer is option C.
