The frequency of oscillation for an LC circuit is given by the formula:

f = 1 / (2π√(LC))

Given that the circuit consists of a 1.0-μF capacitor and a 15-mH coil in series, we can substitute these values into the formula and solve for the frequency:

f = 1 / (2π√(1.0×10^-6 × 15×10^-3))

f ≈ 1.31 kHz

Therefore, the circuit will oscillate at a frequency of approximately 1.3 kHz, which corresponds to choice B.
