Sampling below the Nyquist rate produces
Answer: D
Under-sampling folds the spectrum, so components above half the sampling rate reappear as spurious lower frequencies that cannot afterwards be separated from genuine ones. That irreversibility is why an anti-alias filter precedes every sampler. A loss of signal-to-noise ratio is what quantisation causes. A delay comes from filtering or processing. And the reconstructed bandwidth is limited by half the sampling rate rather than increased.
