What happens if the main riser attached to the RSL breaks?

If the main riser attached to the RSL (Reserve Static Line) breaks, the reserve parachute will still deploy because the other main riser remains intact. The RSL is designed to facilitate the automatic deployment of the reserve parachute if the main parachute is not functioning correctly, but it does so only when the appropriate conditions are met. In the case of the main riser breaking, the reserve system can still operate effectively, allowing the reserve parachute to deploy as intended as it is still connected by the remaining riser. This feature is crucial for enhancing safety during skydiving operations, ensuring that a failure in one part of the system does not prevent the reserve from deploying when needed.

In contrast, the other options imply scenarios where the deployment of the reserve parachute may be either inhibited or lead to other complications, which do not accurately reflect the functionality of the RSL and the overall emergency procedures in skydiving.
