• B. Sterilization in steam cooker at 100${}^o$C for 10 minutes
• C. Heating milk or other liquids to 60${}^o$C to 70${}^o$C for short duration

Answer 1

The correct option is C Heating milk or other liquids to 60${}^o$C to 70${}^o$C for short duration

Pasteuriziation is the process of sterilization. In this, packaged and non-packaged milk and other liquids are heated with mild heat, that is 60${}^o$C to 70${}^o$C for short duration in order to eliminate pathogens and extend shelf-life. The process was first developed by Louis Pasteur in 1864.

Thus, the correct answer is 'Heating milk or other liquids to 60${}^o$C to 70${}^o$C for short duration.'
