Explanation / Answer

1. Actin is directly involved in muscle contraction along with myosin. It is involved in the movement of cilia and flagella when the microtubules slide against each other. It is also involved in the movement of chromosomes and formation of contractile ring during cytokinesis. Moreover, it is also a monomer which can bind ATP. It is also used in eukaryotic flagellum. So options a, b, c, d, e, f and j are correct.
