NEET 2017 Biology question

Hypersecretion of Growth Hormone in adults does not cause further increase in height, because

(1)Growth Hormone becomes inactive in adults
(2)Epiphyseal plates close after adolescenceCorrect
(3)Bones loose their sensitivity to Growth Hormone in adults
(4)Muscle fibres do not grow in size after birth
