Answer

Correct option: D.
$A$ is false but $R$ is true.
The small intestine is the largest part of the alimentary canal. It is about $6.5$ metres long in an adult man. Though small intestine is very long, it is called small intestine because it is very narrow. The length of small intestine differs in various animals depending on the type of food they eat. Meat is a food which is easier to digest. So, tiger which is a carnivorous animal has a shorter small intestine than herbivores.
