Answer:
The correct answer is option B) "A positive feedback loop".
Explanation:
A positive feedback loop is defined as a condition where a reaction produces a molecule that increases the rate of this same reaction. This is what happens with the pepsinogen and the pepsin, since pepsin is the product of the reaction of pepsinogen hydrolysis and pepsin itself can perform the reaction, which in fact increases the rate of reaction.
