If $u(t)$ is the unit step function, then the region of convergence $\text{(ROC)}$ of the Laplace transform of the signal
\[
x(t)=e^{t^{2}}[u(t-1)-u(t-10)]
\]
is
- $-\infty<\operatorname{Re}(s)<\infty$
- $\operatorname{Re}(s) \geq 10$
- $\operatorname{Re}(s) \leq 1$
- $1 \leq \operatorname{Re}(s) \leq 10$
