Answer:
A) actin and myosin is a correct answer.
Explanation:
- Myofibrils are the contractile fiber and they are made of actin and myosin.
- Myofibrils are made of thick myofilaments and thin myofilaments.
- Thick myofilaments are made up of myosin whereas thin myofilaments are composed of actin.
- The functional unit of muscle is Myofibrils and contraction of muscle occurs due to myofibril, when the filaments actin and myosin interact with each other.
Thus Myofibrils are made primarily of (A) actin and myosin.

Seismology is the study of earthquakes, the escalation of waves and the effects they might have. A seismologist is a scientist who is concerned with these studies. They make use of seismographs and other relevant tools to gather essential data which helps in reading the planetary movements and understanding them better. The study does not always predict an earthquake but it helps in predicting the possibility of tsunamis. Seismology enabled the development of tsunami warning systems.
