The extracellular matrix is composed of fibers (such as collagen and elastin) and other proteins (such as laminin and fibronectin). It also functions to allow communication between cells, as it contains signaling molecules and receptors that cells can use to communicate with one another. Therefore, option E (both "it is composed of fibers and other proteins" and "it functions to allow communication between cells" are correct) is the best choice.
