Understand the definition of sterilization: it is the process of completely eliminating all forms of microbial life, including spores.
Recognize that physical agents for sterilization typically involve methods that use physical means such as heat, radiation, or filtration.
Identify the options given: Moist heat (autoclaving), Alcohol, Glutaraldehyde, and Ethylene oxide gas.
Recall that moist heat sterilization (autoclaving) uses pressurized steam to kill microorganisms and is a common physical sterilization method.
Note that alcohol and glutaraldehyde are chemical disinfectants, and ethylene oxide gas is a chemical sterilizing agent, so they are not physical agents.
