For the circle C with the equation x² + y² - 16 - 12y + 64 = 0 match the List I with the List II given below.

	List I		List II
(i)	The equation of the polar of (- 5, 1) with respect to	(A)	y = 0
(ii)	The equation of the tangent at (8, 0) to C	(B)	y = 6
(iii)	The equation of the normal at (2, 6) to C	(C)	13x + 5y = 98
(iv)	The equation of the diameter of C through (8, 12)	(D)	13x + 5y = 98
		(E)	x = 6

The correct match is
