B) Without a carrier, the signal strength of the received station is zero
C) The carrier actually contains the intelligence signal
D) It is needed for the receiver to maintain its sensitivity and selectivity

The carrier signal in an SSB (Single Side Band) receiver is necessary for the demodulator to properly recreate the original intelligence (audio, video, data, etc.) from the modulated signal. The carrier provides a reference frequency against which the modulated sidebands (containing the actual information) can be demodulated or decoded back into a form that resembles the original signal before transmission.
