(B) Urethra

The urethra is the structure that forms a common passage for both urine and sperm in human males. It connects the urinary bladder to the external opening and serves as the channel through which urine and semen pass out of the body. The other options—Oviduct, Ureter, and Vas deferens—are not involved in the passage of urine in males. Oviduct is part of the female reproductive system, while the ureter carries urine from the kidneys to the bladder, and the vas deferens is a duct that transports sperm from the testes to the urethra.

Therefore, the correct answer to the question is (C) Echinoderms.

(D) Cells which are similar in origin, form and function.

Tissues are groups of cells that are similar in origin, form, and function, working together to perform specific tasks in the body. Tissues can be classified into four main types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each type of tissue is composed of cells that share common characteristics and collaborate to carry out specialized functions within the body.
