The correct answer is Option (4)- Urinary Bladder

Urine is stored in the Urinary Bladder before finally being ejected out.

Explanation:

• The excretory system in humans includes organs such as the kidneys, ureters, urinary bladder, and urethra.
• After the kidneys filter blood and produce urine, the urine flows through the ureters, tubes that connect the kidneys to the urinary bladder.
• The Urinary Bladder is a muscular organ that serves as a temporary storage reservoir for urine.
• When the bladder is full, the urine is expelled from the body through the Urethra, a tube connecting the bladder to the external environment.

So, the correct answer is the Urinary Bladder.
