No, I do not agree with the student's statement.

Although the urethra is part of the excretory system (it carries urine out of the body), it also plays an important role in reproduction in males. The vas deferens, which carries sperms from the testes, unites with a tube coming from the urinary bladder. The urethra thus forms a common passage for both urine and sperms. Therefore, the urethra is shared by both the excretory and reproductive systems in males.

• The key fact examiners want: urethra = common passage for urine AND sperms — state this explicitly.
• The student's error is assuming one organ can belong to only one system. In males, the urethra serves a dual function.
• Mention vas deferens uniting with the urinary bladder tube to show how sperms reach the urethra — this earns the justification marks.
• Keep it concise; 3 marks = disagreement (1) + reason/mechanism (1) + conclusion (1).
