The correct option is C Mycotoxins
Fungi grow on certain food items like pickles, murabba, jam, sauce, chutney, etc. The fungal hyphae obtain nutrition for their growth and reproduction by absorbing nutrients from the food item. During this process, fungi releases some chemicals called mycotoxins which makes the food poisonous. They also grow on materials like leather, wood, gunny bags etc., in the presence of moisture.
