The analogy 'FERTILIZE : GROW' represents a cause and effect relationship where fertilizing causes growth in plants. Similarly, 'immunize : resist' shows that immunizing causes resistance to disease in a person. This matches the cause-effect pattern of the analogy. Other options do not fit this cause-effect relationship as clearly: 'nourish : enrich' is more about improvement than direct cause of growth, 'heat : burn' is not always a direct cause-effect (heat may or may not cause burning), and 'graft : multiply' is not a direct cause-effect relationship. Therefore, option A is the best fit.
