The correct option is B epiphyseal plates close after adolescence
Growth Hormone (GH) is produced by the anterior pituitary. Over-secretion of GH stimulates abnormal growth of the body (gigantism) and low secretion of GH results in stunted growth (dwarfism) in children.
In adults, hypersecretion of GH does not cause further increase in height because epiphyseal plates close after adolescence. Epiphyseal plate is a hyaline cartilage plate at each end of a long bone where bone growth takes place.
