Why Is the Zone of Overlap an Important Region of the Sarcomere

Why is the zone of overlap an important region of the sarcomere?

A) The zone of overlap is important because it is where actin filaments are anchored to and overlap nebulin proteins.
B) The zone of overlap is important because it is where myosin filaments are anchored to and overlap titin proteins.
C) The zone of overlap is important because it is where the myosin heads can interact with the thin filaments.
D) The zone of overlap is important because it is where one sarcomere ends and another sarcomere begins.
E) The zone of overlap is important because it is where the troponin proteins bind acetylcholine to generate an action potential that can cause muscle contraction to occur.
