In finish machining of an island on a casting with $$CNC$$ milling machine, an end mill with $$10$$ $$mm$$ diameter is employed. The corner points of the island are represented by $$(0,0), (0,30), (50,30)$$ and $$(50,0)$$. By applying cutter radius right compensation, the trajectory of the cutter will be
A
$$(-5,0), (-5,35), (55,35), (55,-5), (-5,-5)$$
B
$$(0,-5), (55,-5), (55,35), (-5,35), (-5,-5)$$
C
$$(5,5), (5,25), (45,25), (45,5), (5,5)$$
D
$$(5,5), (45,5), (45,25), (5,25), (5,5)$$
