A short-loop, negative-feedback control system involves the target gland's hormone feeding back to the anterior pituitary, suppressing the tropic hormone. In option A, the anterior pituitary hormone feeds back to the hypothalamus, suppressing releasing hormone. This is an example of a short-loop, negative-feedback control system. Option B describes a long-loop, negative-feedback control system. Option C describes a simple endocrine pathway with no feedback control. Option D does not make sense as there is no inhibiting hormone in the posterior pituitary gland.
