The circuit is a simple RC circuit with a capacitor and resistor in series. When S is pushed up, the capacitor charges. When S is pushed down, the capacitor discharges through the resistor. The frequency of oscillation in this circuit can be found using the formula f = 1/(2πRC), where f is the frequency, R is the resistance, and C is the capacitance. Plugging in the given values of R = 10 kΩ and C = 100 nF, we get f = 1/(2π(10 kΩ)(100 nF)) = 318 Hz. Therefore, the answer is A. The frequency does not depend on V₀, as it is determined solely by the values of R and C in the circuit.
