What consequence can a person face if they experience GLOC?

Experiencing GLOC, or G-induced Loss of Consciousness, results in a temporary loss of consciousness due to the effects of high G-forces on the body. This physiological response occurs when the blood flow to the brain is insufficient, often leading to a brief period where the person becomes unconscious. This phenomenon is most commonly encountered in pilots or individuals subjected to rapid accelerations, such as during flight maneuvers or certain high-speed activities.

The other choices, while they may involve some bodily response related to G-forces, do not specifically capture the defining characteristic of GLOC. Therefore, the correct choice is centered on the loss of consciousness itself, which is a primary and notable consequence of experiencing excessive G-forces.
