MCQ (Single Correct Answer)
The system shown in figure below
can be reduced to the form
With
A
$$X = {C_0}s + {C_1},\,\,Y = 1/\left( {{s^2} + {a_0}s + {a_1}} \right),\,z = {b_0}s + {b_1}$$
B
$$X = 1,\,\,Y = \left( {{c_0}s + {c_1}} \right)/\left( {{s^2} + {a_0}s + {a_1}} \right),\,z = {b_0}s + {b_1}$$
C
$$X = {C_1}s + {C_0},\,\,Y = \left( {{b_1}s + {b_0}} \right)/\left( {{s^2} + {a_1}s + {a_0}} \right),\,z = 1$$
D
$$X = {C_1}s + {C_0},\,\,Y = 1/\left( {{s^2} + {a_1}s + {a_0}} \right),\,z = {b_1}s + {b_0}$$
