A line can continue to operate even if it becomes grounded because the grounding does not necessarily interrupt the flow of electricity under certain conditions. When a line is grounded, it creates a parallel path for current to flow, which can allow the system to maintain functionality, especially if the grounding fault is not severe. This is often seen in distribution systems where protective mechanisms are in place to handle ground faults.

In power systems, particularly in three-phase systems, a grounded conductor may still enable the remaining phases to operate normally if designed for such circumstances. Protective devices are also used to detect grounding faults and can isolate the faulted section from the rest of the system to maintain service continuity.

The other options suggest limitations that do not accurately reflect operational realities. Stopping operation entirely in the case of grounding may not always be necessary depending on the system design and safety protocols in place. New lines and conditions like low currents might also not specifically dictate operability; rather, it is the design and management of the electrical system that primarily determine the response to grounding.
