Final answer:
The option to pasteurize an egg in the shell without cooking it or breaking the shell is by submerging it in hot water.
Step-by-step explanation:
The option that can pasteurize an egg in the shell without cooking the egg or breaking the shell is by submerging it in hot water.
Pasteurization relies on applying heat to kill pathogens and reduce the number of microbes without cooking the egg. By submerging the egg in hot water, the heat can penetrate the shell and reach the egg, effectively pasteurizing it.
This method is similar to how pasteurization is used to treat milk and other food products to kill heat-sensitive pathogens while preserving quality.
