Answer:
The correct answer is - a storehouse for good bacteria.
Step-by-step explanation:
The appendix is a finger-like small narrow-sized pouch that founds out from the colon. Initially, it was thought to a vestigial organ that has very little or no function in the human body.
In modern and more recent research suggests that the appendix has a very important role as it works as a reservoir or storehouse for beneficial gut bacteria.
