(c) Growth hormone
Explanation:
Acromegaly is due to hyposecretion of growth/somatotrophic hormone in adults after the closure of epiphysed plate at the end of long bones. Growth hormone is secreted by artesian pituitary gland.
It is characterised by abnormal elongation of limbs and lower jaw giving gorilla like appearance. Hypersecretion of insulin results in hypoglycemia, hunger, sweating and double vision. Hypersecretion of thyroxine results in Grave's disease (also called exopthalmic goiter) which is characterised by increased BMR, heart rate, pulse rate; protrusion of eyes etc.
