Should be C, Should be negative to be having value in final value theorem.

For a closed loop transfer function, roots of the numerator are called zeros and roots of the denominator are called poles. So for stable response poles should be real and negative. So correct option is C.

Only C left side axis to stable.

For a stable system a closed loop pole should lie to the left of the imaginary axis for that it should be real and negative.
