Correct Option: A

Given Ya =		2		0		mS.
		0		10

Its Z-parameter equivalent can be given as

Z =	1		0
	2 × 10–3		1
	0		10 × 10–3

=		500		0
		0		100

The equivalent Z-parameter at terminals AA′ and BB′

Zeq =		500	0		+		100	100
		0	100				100	100

=		600		100
		100		200

or V₁ = 600 I₁ + 100 I₂ (A)
V₂ = 100 I₁ + 200 I₂ (B)
V_S = 60 I₁ + V₁ = 660 I₁ + 100 I₂ (C)
V₂ = V₀ = – 300 I₂ (D)
and V₂ = 100 I₁ + 200 I₂ (E)
from (D) and (E)
– 300 I₂ = 100 I₁ + 200 I₂
or – 500 I₂ = 100 I₁
or – 5 I₂ = I₁

From equation (C)
V_S = 660. (– 5 I₂) + 100 I₂
or V_S = – 3300 + 100 I₂ = – 3200 I₂

Now,	V0	=	–300 I2	=	3
	Vs		–3200		32

Hence alternative (A) is the correct choice.
