In the feedback control system shown in the figure below G(s) = 6 / [s(s + 1)(s + 2)] R(s), Y(s), and E(s) are the Laplace transforms of r(t), y(t), and e(t), respectively. If the input r(t) is a unit step function, then
A
limt → ∞ e(t) = 0
B
limt → ∞ e(t) = 1/3
C
limt → ∞ e(t) = 1/4
D
limt → ∞ e(t) does not exist, e(t) is oscillatory

Correct : B
