The correct option is C Fungi

A wide range of fungal, bacterial and viral pathogens, affect the yield of cultivated crop species. Crop losses can often be significant, up to 20-30 per cent, or sometimes even total. Some of the diseases caused by fungi are rusts, e.g., brown rust of wheat, red rot of sugarcane and late blight of potato. Leaf and brown rust is caused by Puccinia triticina. Disease caused by bacteria is black rot of crucifers. Diseases caused by viruses are tobacco mosaic, turnip mosaic, etc.

So, the answer is C.
