Physical indicators are used primarily to track the temperature and time of a sterilization cycle, but they do not provide information about the effectiveness of the process in killing microorganisms. Option B is incorrect because mechanical monitoring is not a type of sterilization monitoring either. Mechanical indicators are used to ensure that proper conditions, such as pressure and temperature, are met during the sterilization cycle. They do not provide information about the presence of microorganisms. Option D is incorrect because operational monitoring is not a type of sterilization monitoring. Operational monitoring involves checking the functionality of equipment and processes, but it does not indicate whether sterilization was
