The correct option is A Anterior pituitary
The anterior pituitary (also called the adenohypophysis or pars anterior), is the glandular, anterior lobe, that together with the posterior lobe, the (posterior pituitary, also known as the neurohypophysis) makes up the pituitary gland (hypophysis). The anterior pituitary regulates several physiological processes including stress, growth, reproduction, and lactation. The production of thyroxine is stimulated by TSH (Thyroid stimulating hormone) and the gonads are stimulated by gonadotropins (FSH and LH) which are secreted by the anterior pituitary gland. Thus, the correct answer is option A.
