The condition CIPA (Congenital Insensitivity to Pain with Anhidrosis) affects the ability to feel pain and temperature, which primarily involves the dysfunction of thermoreceptors (which sense temperature) and nociceptors (which are a type of mechanoreceptor that sense pain). Since "nociceptors" is not listed among the options, the best option that describes the affected sensory receptors is:
thermoreceptors and mechanoreceptors
