Practice question

Correct option is B, Alimentary canal. In Digestive System, the accurate description is Alimentary canal, and that is what you should commit to memory. Keep the definition tight and the role clear — Alimentary canal is the option that correctly names the structure, process, or principle asked for in Digestive System. Then Alimentary canal is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Alimentary canal. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
