Which resistor changes its resistance in response to light intensity?

The light-dependent resistor (LDR) is designed specifically to change its resistance based on the intensity of light falling on it. When light intensity increases, the resistance of the LDR decreases, allowing more current to flow through the circuit. Conversely, when the light intensity diminishes, the resistance increases, reducing the current flow. This property makes LDRs particularly useful in applications like light sensors, streetlights that turn on at dusk, and automatic lighting systems, where the response to varying light levels is crucial.

Other components like potentiometers are used to manually adjust resistance within a circuit, thermistors change resistance in response to temperature variations, and inductors are primarily concerned with the effects of changing current and magnetic fields rather than light. This specificity of the LDR's response to light intensity makes it the correct choice for this question.
