Explanation
The exact mechanism of myosin-actin detachment in the context of rigor mortis is somewhat unclear here, since rigor mortis is classically defined by the myosin and actin remaining LOCKED together due to the unavailability of ATP, rather than detaching — this option and stem are worth double-checking against the source.
