Explanation:
(Refer to the figure below)
Do not assume the centre of this circle is at (0, 0)
If centre is at (0, 0)
Col. A: \(16π\)
Col. B: \(16π\)
i.e. Col. A = Col. C
If the centre is not at origin
Col. A > Col. B
Hence, option D

is it C,
because both point lies on circle that on extreme region of circle which makes diameter =8 and radius =4
applying formula of area of circle=16*3.14.
