The correct answer is (a) True

Explanation: Plant diseases are broadly classified into two categories, nonparasitic and parasitic. Nonparasitic diseases are non-transmissible and are caused by physiological disorders due to defective heredity or unfavourable environment. Parasitic diseases are transmissible diseases which are caused by various categories of pathogens.
