When the bladder is full and ready to release urine, the relaxation of the urethra is crucial. It allows the urethral muscles to loosen and open up, creating a wider pathway for the urine to flow from the bladder to the outside of the body. This relaxation of the urethra is coordinated with the contraction of the bladder muscles to create a coordinated and controlled release of urine. Without the relaxation of the urethra, it would be difficult for urine to pass through and be expelled from the body.Hence, the correct answer is option 1.
