• A. A-(iii), B-(ii), C-(iv), D-(i), E-(v)
• B. A-(ii), B-(v), C-(i), D-(iv), E-(iii)
• C. A-(iii), B-(iv), C-(i), D-(v), E-(ii)
• D. A-(iv), B-(iii), C-(i), D-(ii), E-(v)

Answer 1

The correct option is C A-(iii), B-(iv), C-(i), D-(v), E-(ii)

Sphincter ani Interus guards the terminal of the alimentary canal.

Cardiac sphincter lies between oesophagus and anterior stomach.

Sphincter of Oddi lies in the opening of hepatopancreatic ampulla into duodenum.

Ileocaecal sphincter lies between small and large intestine and pyloric sphincter lies between duodenum and posterior stomach.

So, option C is the correct option.
