Set of values of '

h

' for which the number of distinct common normals of

(x-2)^2=4(y-3)

and

x^2+y^2-2 x-h y-c=0(c>0)

is 3 , is

View answer and explanation

Correct option: D

(10, \infty)

Option D (

(10, \infty)

) is correct because the condition for the number of distinct common normals of the given parabola and circle to be 3 leads to this interval for the values of 'h'.
