Tropic hormones are essentially messengers (generally produced by the pituitary) aimed at endocrine glands/organ, to signal them to enlarge and produce a particular hormone or to bring out a desired overall effect.
Anti-diuretic hormone (C, also called vasopressin or agipressin) is a hormone produced by the pituitary that acts on the kidneys, to regulate water content within the body. Therefore, this option is incorrect.
Follicle stimulating hormone (B) encourages hormone production by the gonads and Thyroid stimulating hormone (D) encourages hormone production by thyroid. Therefore, they are tropic hormones.
Somatotropin (A, or growth hormone), is produced by the pituitary that has several complex overall effect on the body growth and therefore, in effect, it is not a tropic hormone. However, somatotropin facilitates the production of Insulin-like growth factor by the liver, and therefore, it could be deemed a tropic hormone in that regard.
Therefore, options A, B and D are correct.
