What is the range of values of a and b for which the linear time-invariant system with impulse response \(h\left( n \right) = \left\{ {\begin{array}{*{20}{c}}{{a^n},}&{n \ge 0}\\{{b^n},}&{n < 0}\end{array}} \right.\) is stable?

• A. Both |a|< 1 and |b|> 1 are satisfied
• B. Both |a|> 1 and |b|< 1 are satisfied
• C. Both |a|> 1 and |b|> 1 are satisfied
• D. Both |a|< 1 and |b|< 1 are satisfied
