The correct option is C Only statement (i) and statement (iii) are correct.

The digestive system of the human body comprises a group of organs working together to convert food into energy for the body.
$\bullet$ The chemical process of digestion begins in the oral cavity or mouth; wherein the food particles are thoroughly mixed with saliva.
$\bullet$ Saliva contains an enzyme, salivary amylase that breaks down complex carbohydrate into simple maltose. It moistens the food particles and facilitates swallowing.
