radiated food can be safely stored for a longer time because radiation
1. prevents air oxidation
2. prevents air reduction
3. kills bacteria
4. causes bacteria to mutate
is it 3 ?
yes.
Yes, the correct answer is 3. Radiated food can be safely stored for a longer time because radiation kills bacteria. This helps to slow down the spoilage process and extends the shelf life of the food.
To arrive at this answer, you can eliminate options 1 and 2 because radiation does not directly prevent air oxidation or air reduction. Option 4 is also incorrect because radiation does not cause bacteria to mutate in a significant way. So, the remaining option, 3, is the correct choice.
