Question

the phase of the cell cycle in which the cell membrane pinches in and splits the cell into two
cytokinesis
metaphase
prophase
telophase
anaphase

Explanation:

In the cell cycle, cytokinesis is the phase where the cell membrane pinches (cleavage furrow in animal cells) to divide the cell into two daughter cells. Metaphase (chromosomes align), Prophase (chromosome condensation), Telophase (nuclear envelope reforms), and Anaphase (chromosomes separate) do not involve the final cell - splitting via membrane pinching.

Answer:

Cytokinesis
