B Correct answer
Explanation

The actin-based filaments formed by cytoskeleton in order to sense the external environment are called filopodia. They are rich in actin-binding proteins, e.g. fascin and fimbrin. Filopodia are slender cytoplasmic projections that form focal adhesion with the substrate linking it to the cell surface.
