• A. All bacteria
• B. All living organisms
• C. Vegetative forms of bacteria
• D. Vegetative forms of all pathogenic bacteria

Answer 1

The correct option is D Vegetative forms of all pathogenic bacteria

Pasteuriziation is the process of sterilization. In this, packaged and non-packaged food stuffs 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. This process frees food stuffs of vegetative forms of all pathogenic bacteria. The process was first developed by Louis Pasteur in 1864.

Thus, the correct answer is 'Vegetative forms of all pathogenic bacteria.'
