Direct answer
A suspended load seeks equilibrium with its center of gravity below the hook, so an off-center hookup can create uncontrolled movement. On the NCCCO Practice Test, treat What can happen when the hook is not positioned over the load's center of gravity before hoisting as a concept to understand, not an answer letter to memorize. Review how it affects safety, code interpretation, jobsite decisions, or timed problem solving, then answer a short practice set tied to Crane safety concepts, Basic load chart practice, Signals and communication.
