What is the term for an inducible whole-body resistance in plants in response to a wide range of pathogens and abiotic stressors?

A) systemic acquired resistance
B) hypersensitive response
C) vernalization
D) abscission
E) circadian rhythm

The term for an inducible whole-body resistance in plants in response to a wide range of pathogens and abiotic stressors is systemic acquired resistance (SAR). Hypersensitive response is a localized response to pathogens, vernalization is a process of inducing flowering through exposure to cold temperatures, abscission is the shedding of plant parts, and circadian rhythm is a biological process that regulates behaviors and physiological processes in plants and animals.
