How does the cycle of cross-bridge formation and breakage lead to muscle contraction?

How does the cycle of cross-bridge formation and breakage lead to muscle contraction?
  1. By breaking the cross-bridge
  2. By increasing the cross-bridge formation between actin and myosin
  3. By reducing the ‘I’ bands and retaining the length of the ‘A’ bands
  4. By pumping calcium ions back to the sarcoplasmic cisternae

Solution

The cycle of cross-bridge formation and breakage causes further sliding of actin
