Solution

The correct option is B

Mosaic disease


Mosaic diseases are caused by plant viruses, such as cucumber mosaic virus, that are mostly spread by insects, especially aphids and leafhoppers. It causes leaves to wrinkle and turn brown and also causes stunted growth of plants. Quick wilt is a fungal disease which attacks both the root system as well as the aerial parts of the plant. Blights are caused by bacterial or fungal infestations, which usually attack the shoots and other young, rapidly growing tissues of a plant. Bud rot is one of the most devastating fungal diseases found in plants.
