Find the number of poles in the left half plane (LHP), the right half plane (RJP) and on the jω-axis for the feedback control system as shown. Is the system stable?

• A. 1 LHP poles; 3 RHP poles; 0 jω poles; system is stable
• B. 2 LHP poles; 2 RHP poles; 0 jω poles; system is unstable
• C. 2 LHP ploes; 2 RHP poles; 0 jω poles; system is stable
• D. 1 LHP poles; 3 RHP poles; 0 jω poles; system is unstable
