B) Biotrophy
C) Hemibiotrophy
i) where the plant cells remain alive throughout infection
ii) where the plant cells are killed in advance of infection 
iii) extensive plant tissue damage at initial stages
iv) where the pathogen initially keeps cells alive but at later stages of the infection, kills them
