Answer 1

The correct option is D Both b and c


Fungal infection

• Fungi are heterotrophic and can derive nutrition from the organic matter present in food.
• Fungi mainly spoil food that is kept in a warm and humid environment as these conditions are suitable for its growth.

Bacterial infection

• Bacteria like Staphylococcus can multiply and derive nutrition from food, thus spoiling it.
• Preservation using low temperatures reduces enzymatic activity thus inhibiting the growth of these bacteria.
