Final answer:
The correct ruling in this scenario is 'No lift' as the spotter/loader interfered with the lifter's performance.
Step-by-step explanation:
In the scenario where a spotter/loader grabs the bar before the head judge indicates, the correct ruling is d. No lift. This is because the spotter/loader's action interferes with the lifter's performance and violates the rules of the sport. The spotter/loader should wait for the head judge's signal before touching the bar.
