(a) The system response depends on present, past, and future inputs. Hence, it is dynamic.
(b) Since the output depends on the future input, it is non-causal.
(c) The output due to the delayed input is not the same as the delayed output. Hence, the system is time variant.
(d) The weighted sum of the output is the same as output due to the weighted sum of the input. Hence, it is linear.
(e) If the input is bounded, the output is also bounded. The system is stable.

y(t)=x(10 t)
