What type of hormones are secreted by troph cells in the anterior pituitary gland?
a. releasing hormones
b. stimulating hormones

Option (b). stimulating hormone.

Explanation:

The pituitary gland is an endocrine gland, present at the base of the brain. The anterior lobe of pituitary consists of various endocrine cells or troph cells that synthesize and secret various hormones.

The hormones released by these cells are mainly stimulating hormones that regulate functions of some other glands. For example, TSH (thyroid stimulating hormone) and FSH (follicle stimulating hormone) are secreted by anterior pituitary gland that regulate function of thyroid gland and ovaries, respectively.  

Thus, the correct answer is option (b).
