Negative feedback will stop the release of this hormone.

Explanation:

Negative feedback is a strategy for regulating the organism that tries to maintain the internal balance of the body, causing an action contrary to the action that is causing the imbalance. That way we can understand that if in a hypothetical situation, a boy has low blood pressure and his pituitary started to produce a hormone to maintain the water balance, the negative feedback will interrupt the release of this hormone, so that his pressure returns to normal.

the bullets go in this order.
