Correct option is A)

The expression for  acceleration due to gravity is given by
as we know the radius of the earth at poles is minimum, so acceleration due to gravity will be maximum at poles because g is inversely proportional to .
also, the net acceleration due to gravity is affected (decreases) by centrifugal force due to rotation of the earth.
poles are less affected by rotation also their radius is small so poles have maximum value of g.
so the best option is A.
