Explanation:
Generally, hormones are chemical messengers that are secreted in a particular location and transported to another location to effect a physiological response. However, some set of hormones secreted by an endocrine gland functions in stimulating or regulating the secretion of other hormones by another endocrine gland. These group of hormones are called TROPIC HORMONES.
As stated in this question, the anterior pituitary gland, which is considered to be the "MASTER GLAND" secretes an hormone that controls the secretion of another hormone by adrenal gland. The hormone secreted by the PITUITARY GLAND is a TROPIC HORMONE. An example of tropic hormone is ADRENOCORTICOTROPIC HORMONE (ACTH) secreted by anterior pituitary gland.
