The severity of an electric shock is determined by four factors: how much current flows through the body, the path the current takes through the body, the body's resistance at the points of contact, and how long the current flows. The amount of current is what drives the physiological effects—more current means a greater risk of muscle contractions, burns, and problems like heart rhythm disturbances. The path matters because current through critical areas, such as the chest or heart, is much more dangerous than through other parts of the body. Resistance influences how much current actually passes for a given voltage; wet skin lowers resistance and allows more current to flow, while dry skin raises resistance and reduces it. Time is important because longer exposure delivers more energy to tissues, increasing the likelihood of burns and internal damage.

Other options mix factors like voltage, temperature, humidity, or technical wiring details, which may affect the chance of experiencing a shock but do not directly determine the shock’s severity in the same way those four do. Therefore, the best answer is the one that lists Amount, Path, Resistance, and Time.
