Solution
The correct option is D hypothalamus
GH- RH ( Gonadotropic releasing hormone ) secretes growth hormone (GH). GH or STH (Growth or Somatotropin Hormone) stimulates body growth, protein, fat, and carbohydrate metabolism. The hormone is secreted by adenohypophysis (anterior pituitary). Hypersecretion of this hormone during the period of skeletal growth causes gigantism characterized by excessive growth of bones, with the enlargement of internal organs as well. Hypersecretion in adulthood causes acromegaly. Here the bones become abnormally thick due to ossification of periosteum and thickening of soft tissues as well.
