Which of the following sarcomeres is labelled correctly ?

Each myofibril has alternate dark and light bands on it. A detailed study of the myofibril has established that the striated appearance is due to the distribution pattern of two important proteins – Actin and Myosin.
- wherein
Actin filaments are thinner as compared to the myosin filaments, hence are commonly called thin and thick filaments respectively.
