A stable Linear Time Invariant (LTI) system has a transfer function $${\text{H}}\left( {\text{s}} \right) = \frac{1}{{{{\text{s}}^2} + {\text{s}} - 6}}.$$ To make this system causal it needs to be cascaded with another LTI system having a transfer function H1(s). A correct choice for H1(s) among the following option is
A. s + 3
B. s - 2
C. s - 6
D. s + 1
