Correct Option: C

KCL at node A, and apply Laplace transform

VA(s) – Ei(s)	+ VA .Cs +	VA – E0(s)	= 0 …(i)
R		R

[˙.˙ V_B = E_o(s)]
KCL at node B.

E0(s)	+	E0(s) – VA	= 0 …(ii)
1/Cs		R

from equation (ii)
V_A= E_o(s) [RCS + 1] …(iii)
Now by using equations (i) and (iii) and on putting T = RC we get

Eo (s). [Ts + 1] =	Ei(s) + E0(s)
	(Ts + 2)

or

or Eo (s).		Ts + 1 -	1		=	Ej(s)
			Ts + 2			(Ts + 2)

or	E0(s)	=	1
	Ej(s)		T2s2 + 3Ts + 1
