The hormone that increases bile flow by increasing its formation is the Cholecystokinin (CCK) hormone.

Here's a step-by-step explanation:

1. When fatty, rich food enters the stomach and then the small intestine, the cells in the lining of the small intestine secrete CCK hormone.

2. This hormone then enters the bloodstream.

3. When CCK reaches the gallbladder, it binds to receptors on the surface of the gallbladder.

4. This binding signals the gallbladder to contract and release stored bile into the small intestine.

5. Additionally, CCK also signals the liver to produce more bile to replenish the gallbladder's supply.

6. Therefore, the CCK hormone increases bile flow by increasing its formation.

So, the correct answer is CCK hormone.
