Explanation

Now the center of the circle is (7,3). Since the circle intersects the x axis at 2 points it means that the radius is greater 3 or the y coordinate of the center of the circle.

Hence the possible values of the radius are C, D and E.

Correct answer must be "c", since the radius must also be smaller than 7 as there is no intercept with the y-axis.
