The correct option is (a) Double sideband suppressed carrier amplitude modulated waveform

To elaborate: The BPSK signal is equivalent to a double sideband suppressed carrier amplitude modulated waveform, where cos(2πft) is applied as the carrier. Hence, a BPSK signal can be generated using a balanced modulator.
