Correct Option: C

The given figure:

The transmission matrix is given by:

	V1		=		V2			A	B
	l1				-l2			C	D

V₁ = AV₂ – BI₂ . . . …(i)
and I₁ = CV₂ – DI₂ . . .…(ii)

From figure:
V₁ = (I₁ + I₂) × 1/y
and

V2 = I2z +		I1 + I2		= l2z +	I1	+	I2
		y			y		y

or
I₁ = – I₂ (1 + yz) + V₂y . . . . .…(iii)
and V₁ = – I₂z + V₂ …. . . . .(iv)
On comparing equation (i) and (ii) with (iii) and (iv), we get:

	A	B		=		1	z
	C	D				y	1+yz

Hence alternative (C) is the correct choice.
