Which one of the following pairs is NOT correctly matched; (input \(=x(t)\) and output \(=y(t))\)
(a) Unstable system
\(\frac{d y(t)}{d t}-0.1 y(t)=x(t)\)
(b) Nonlinear system .... \(\frac{d y(t)}{d t}+2 t^{2} y(t)=x(t)\)
(c) Noncausal system
\(y(t)=x(t+2)\)
(d) Nondynamic system .... \(y(t)=3 x^{2}(t)\).
