The correct option is (b) High-pass Filter

The explanation is: We know that, the position of Resistance (R) and Capacitance (C) determines whether it is Low-pass Filter or High-Pass Filter. If R is connected directly to source and the capacitor connected in parallel to it, then it is a Low-pass Filter and if the position of R and C are inter change then high pass filter is formed.

Here since R and C are in series and also R is not connected directly to the power source, hence the filter is a High-pass Filter.
