Small tubular organ connected to the cecum which has no known function:
A
Stomach
B
Gallbladder
C
Colon
D
Appendix
Explanation: 

Detailed explanation-1: -appendix, formally vermiform appendix, in anatomy, a vestigial hollow tube that is closed at one end and is attached at the other end to the cecum, a pouchlike beginning of the large intestine into which the small intestine empties its contents. It is not clear whether the appendix serves any useful purpose in humans.

Detailed explanation-2: -The cecum and appendix are the initial parts of the large intestine and are situated in the right iliac fossa. The appendix is a narrow wormlike structure arising from the posteromedial wall of the cecum about 2 cm below the ileocecal junction and is not constant in its position.

Detailed explanation-3: -The appendix has been found to play a role in mammalian mucosal immune function. It is believed to be involved in extrathymically derived T-lymphocytes and B-lymphocyte-mediated immune responses. It is also said to produce early defences that help prevent serious infections in humans.

Detailed explanation-4: -The function of the appendix is to maintain the gut flora by protecting the good bacteria that are important in digestion. One more role of the appendix is to maintain the good germs in the immune system whereas the caecum helps in absorbing the salts and the fluids that are left after the digestion process.
