Final answer:
An antibiotic solution is not used for terminal sterilization of tissue; rather, ethylene oxide, irradiation, and dry heat are commonly employed methods.
Correct option is c
Step-by-step explanation:
The substance not used for terminal sterilization of tissue is antibiotic solution. Terminal sterilization refers to the process of sterilizing products in their final packaging, ensuring they are free of viable microbes. The methods used for terminal sterilization of tissues include ethylene oxide gas, which is a highly penetrating alkylating agent capable of sterilizing within plastic bags and is suitable for heat-sensitive items, and irradiation, particularly gamma sterilization, which is effective for sterilizing heat-sensitive and packaged materials.
Dry heat, though a form of sterilization, is applied for elongated periods at high temperatures and is less common for tissue sterilization due to its lower penetrative ability compared to moist-heat sterilization. However, antibiotic solutions are not used for terminal sterilization because, although they can prevent the growth of microbes, they do not ensure the complete sterility of the tissues.
