The suitable option will be - B
B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.
Explanation:
Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.  
Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.  
So, we can say that option B is correct.

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Mitosis is important because the organism must: 
1. replace cells that have worn out or died 
2. repair tissue that is damaged 
3. add cells in order to grow 
4. make new kinds of cells in order to develop
