• A. Colchicine treatment
• B. X-ray treatment
• C. Breeding with wild relatives
• D. Hormone treatment.

Answer 1

Answer: (C)

Breeding with wild relatives

Disease control in the plant is achieved by the process of breeding with wild relatives. Wild varities can sustain extreme weather changes and can survive through many odds without any external chemical treatment. So, breeding with these varities can help to get disease resistant varieties. Plant cultivation such as crop rotation uses of pathogen-free seeds, pesticide, control of field moisture can also resist the plant disease.

So, the correct option is C.
