L or C.<\/p>\n<p>The resonance frequency of an R-L-C series circuit is given by the following formula:<\/p>\n<p>$$f_r = \\frac{1}{2\\pi\\sqrt{LC}}$$<\/p>\n<p>As you can see, the resonance frequency is inversely proportional to the square root of the inductance and capacitance. This means that increasing the inductance or decreasing the capacitance will increase the resonance frequency, and vice versa.<\/p>\n<p>Option A is incorrect because the resistance does not affect the resonance frequency. The resistance only affects the amplitude of the current through the circuit.<\/p>\n<p>Option B is incorrect because the inductance does affect the resonance frequency. As I mentioned above, increasing the inductance will increase the resonance frequency.<\/p>\n<p>Option C is incorrect because the capacitance does affect the resonance frequency.
