The main regulatory function is the homeostatic functions which are involved in maintaining the internal condition of the body like temperature, osmolarity and others. Each function is controlled by the different nuclei present in the hypothalamus.
In the given case, if the hypothalamus is injured or disrupted than the most likely disrupted function will be the regulation of the temperature.
Thus, Option-A is correct.
