Option (b) represents the graph of r = 4 sin θ.
"A polar curve is a shape constructed using the polar coordinate system."
We have been given a function r = 4 sin θ .
We need to determine the graph for given function.
We know, r = a sin θ is a circle where “a” is the diameter of the circle that has its bottom-most edge at the pole (origin).
This means, r = 4 sin θ is a circle that has bottom-most edge at the origin (0, 0).
In the graph (b), a circle has bottom-most edge at the pole.
Therefore, the correct graph is option (b)
