Microfilaments are a component of the cell's cytoskeleton and these are made up of the actin protein. They are involved in the cellular movement. Thus, the correct option is B.
What are Microfilaments?Microfilaments are also called as actin filaments, as they consist of two intertwined strands of a globular protein, which is known as actin protein. In association with myosin, microfilaments help to generate forces that are used in cellular contraction and cellular movements. During cell division, these filaments results into dividing cell to pinch off into two daughter cells and are involved in amoeboid movements of certain types of cells.
Microfilaments assist with cellular movement due to the presence of actin filaments. Actin filament works with another protein called myosin to produce muscular movements, cell division, and cytoplasmic streaming during cell division. Microfilaments keep the organelles in place within the cell.
Therefore, the correct option is B.
