Answer:
meiosis i think
Step-by-step explanation:
there are chromosomes, so therefore it couldn't be mitosis, because it occurs in plant cells, it splits into four separate sex cells, so it is meiosis. it couldn't be fertilization because the egg hasn't turned into a zygote, or fertilized egg, and it couldn't be budding because budding only needs one parent, and the diagram shows two, so it must be meiosis.
