All of the choices listed can stimulate thirst. Drying the mucosa of the mouth and pharynx and stimulation of osmoreceptors both indicate dehydration or a need for fluid intake. Angiotensin II acting on the hypothalamus and an increase in the osmotic pressure of interstitial fluid within the hypothalamus are both signals from the body to the brain that fluid intake is necessary. Therefore, all of the answers are correct.
