Option A represents the correct sequence of parts in the human alimentary canal.

Food enters the human digestive system through the mouth (buccal cavity), then passes down the pharynx and oesophagus to the stomach. From the stomach, it moves into the small intestine, then the large intestine, and finally indigestible material is eliminated through the anus. This represents a unidirectional flow.

The alimentary canal is a continuous tube extending from the mouth to the anus. The small intestine is where most digestion and absorption occur, and it is located between the stomach and the large intestine. The large intestine primarily absorbs water and electrolytes and forms faeces before excretion. The sequence in option A accurately reflects this anatomical pathway.
