Solution
The correct option is A filamentous actin
Each actin (thin) filament is made of two ‘F’ (filamentous) actin molecules helically wound around each other.
Each ‘F’ actin is a polymer of monomeric ‘G’ (globular) actins. Two filaments of another protein, tropomyosin, also run close to the ‘F’ actin molecules throughout their lengths. Troponin is a complex protein, which is distributed at regular intervals on tropomyosin.
