The correct answer to this question is A, Considered contractile proteins. Actin and myosin are proteins that work together to form the muscle cells contractile filaments. These proteins also work to help cells motion. They can be found in the eukaryotic cells.

Actin is a thin, short filament, while myosin is thick and long. Actin filaments are made of three proteins, which are actin, tropomyosin, and troponin, while myosin filaments are only made of two proteins, myosin, and meromyosin. While both filaments are found in A bands, actin can also be found in I bands. Another difference between them is that actin filaments don't have cross bridges, while myosin filaments do.
