Select the correct option for the following matches:

List-$I$	List-$II$
$(1)$ Metaphase-$I$	$(a)$ Number of chromosomes becomes half of the parent cell
$(2)$ Anaphase-$I$	$(b)$ Each chromosome splits at the centromere to form chromatids
$(3)$ Anaphase-$II$	$(c)$ Homologous chromosomes form pairs at the equatorial plate
$(4)$ Telophase-$II$	$(d)$ Homologous chromosomes move towards opposite poles

Name the stage of the cell cycle at which the following events occur:
