The persistence of the nuclear envelope and the formation of an intranuclear spindle are characteristic of ..........

Select the correct match for $X$ and $Y$:

Column $X$	Column $Y$
$(1)$ Karyokinesis	$(P)$ Completes cell division
$(2)$ Cytokinesis	$(Q)$ Formation of multinucleated condition
$(3)$ Interkinesis	$(R)$ Period from prophase to telophase
$(4)$ Syncytium	$(S)$ Stage between two meiotic divisions

Identify the odd one out:

Statement $P$: The phase between two successive meiotic divisions is called interkinesis.
Statement $Q$: The period between two successive cell divisions is called the cell cycle.

Statement $P$: Centrioles duplicate during the $S$ phase.
Statement $Q$: During prophase,centrioles separate from each other and move towards opposite poles of the cell.

In which type of cell division does spindle formation not occur?
