Practice question

Correct option is C, K+. In Sensory System Ear Physiology, the accurate description is K+, and that is what you should commit to memory. Keep the definition tight and the role clear — K+ is the option that correctly names the structure, process, or principle asked for in Sensory System Ear Physiology. Then K+ is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto K+. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
