The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.

One of the most important functions of vitamin B6 is its role in protein metabolism as the vitamin B6 coenzymes are required to metabolise amino acids. The coenzymes participate in reactions that allow a cell to synthesize nonessential amino acids. Hope this helped!
