The charge time for a capacitor in an RC circuit is determined by the time constant τ = RC. Without the figure, we can't see the specific values, but assuming the forward resistance of the diode (15 Ω) is added to the circuit's resistance to calculate the time constant, and given the options, it seems the calculation leads to a charge time characteristic of a small time constant, which is typically in the range of microseconds (μS) for small RC circuits.
