Explanation:

Question (about uterine contraction feedback)

In positive feedback, a change is amplified. Uterine contractions during birth: as contractions occur, they stimulate more contractions (via oxytocin), increasing the process until birth. Negative feedback reduces deviation (e.g., temperature regulation), inhibitory stops a process, deviating is not a feedback term. So the answer is positive.

Positive - feedback systems enhance or accelerate a change. They don't ignore or have no effect; and they do exist in human systems (like blood clotting, birth). So "accelerate a change" is correct.

"Auto - " means self. Autoimmunity is when the immune system attacks self - tissues (self - immunity). Homo - is same (not self in immunity context), passive/active relate to how immunity is acquired, not self - immunity.

Answer:

B. positive (assuming the options are labeled with letters, if original labels were A:negative, B:positive, C:inhibitory, D:deviating)
