Cytokinesis in animal cells involves: a) Alignment of the spindle along the equatorial plane. b) Formation of a cleavage furrow. c) Pinching in the original cell wall to produce a new cell wall between daughter cells. d) Contraction of a ring of actin microfilaments. e) Development of a cell plate that grows out until it reaches the plasma membrane.

The correct answer will be options-B and D

Explanation:

Cytokinesis is the process of cell division which divides the cellular components along with the nuclear component. The cytokinesis takes place after the completion of M-phase which differs in both animal and plant cell.

In an animal cell, the cytokinesis begins by the formation of furrow which eventually pinches off to two cells.

The formation of the furrow is a complex process and requires the microtubules like an actin-myosin ring which gets established in which the actin filaments from the ring. The myosin filaments pull the actin filaments and then forms the ring.

Thus, options-B and D are the correct answer.
