The correct answer is: Diode.
A diode is a semiconductor device that allows current to flow in one direction only. It is used to “block” DC in an electronic circuit by allowing current to flow in one direction and blocking it in the other direction.
A resistance is an electrical component that opposes the flow of current. It is measured in ohms (Ω). The higher the resistance, the more the current is opposed.
A capacitance is an electrical component that stores charge. It is measured in farads (F). The higher the capacitance, the more charge is stored.
An inductance is an electrical component that stores energy in a magnetic field. It is measured in henries (H). The higher the inductance, the more energy is stored.
In conclusion, a diode is the only circuit element that can be used to “block” DC in an electronic circuit.
