I, II and IV processes are correct for given statement.
Self-incompatibility is a genetic mechanism, i.e. genetic control for self-fertilisation by preventing self-pollination, i.e. from the same flower or other flower of the same plant from fertilising the ovules by inhibiting pollen germination or pollen tube growth in the pistil. It ensures cross-pollination.
Thus, option (d) is correct.
