Solution

The correct option is B G-actin
Skeletal muscle fiber is made up of two types of filaments. They are thick filament(myosin) and thin filament(actin).
Each actin (thin) filament is made of two ‘F’ (filamentous) actins helically wound to each other. Each ‘F’ actin is a polymer of monomeric ‘G’ (Globular) actins.
Hence monomeric actin is known as G-actin.
So,the correct answer is 'G-actin'.
