Let h(t) denote the impulse response of a causal system with transfer function $$\frac{1}{{{\text{s}} + 1}}.$$  Consider the following three statements:
S₁: The system is stable.
S₂: $$\frac{{{\text{h}}\left( {{\text{t}} + 1} \right)}}{{{\text{h}}\left( {\text{t}} \right)}}$$  is independent of t for t > 0.
S₃: A non-causal system with the same transfer function is stable.
For the above system,
