It belongs to the group of passive elements, because as a result of its operation, the current can only decrease, that is, unlike active elements, passive ones by themselves cannot amplify the signal. What from the second Kirchhoff’s law and Ohm’s law means that when current flows across the resistor, the voltage drops, the value of which is equal to the value of the flowing current multiplied by the resistance value. So I choose high voltage resistor

I don’t think so. A resistor resists the current flowing through the circuit whereas a short circuit is when there is ‘free-flowing’ current through the circuit.
