Identify the correct statements: $(1)$ Synapsis occurs between homologous chromosomes during prophase $I$ of meiosis. $(2)$ Centromeres split during anaphase $I$ of meiosis. $(3)$ Spindle fibers completely disappear during telophase of mitosis. $(4)$ Nucleoli reappear during telophase $I$ of meiosis.

Match the following columns correctly:

$(E)$ Cytokinesis	$(v)$ Formation of multinucleated condition
