An LTI system having transfer function $$\frac{{{s^2} + 1}}{{{s^2} + 2s + 1}}$$ and input x(t) = sin(t + 1) is in steady state. The output is sampled at a rate ωs rad/s to obtain the final output {y(k)}. Which of the following is true?
A. y is zero for all sampling frequencies ωs
B. y is nonzero for all sampling frequencies ωs
C. y is nonzero for ωs > 2 but zero for ωs < 2
D. y is zero for ωs > 2 but nonzero for ωs < 2
