Best answer
Right option is (c) By studying the genetic constitution of the plant

To elaborate: Resistance of the host plant is the ability to prevent the pathogen from causing disease and is determined by the genetic constitution of the host plant. Before breeding is undertaken, it is important to know about the causative organism and the mode of transmission.
