Note that an odd function is :
It means that for example, in a function f(x), the point is (x, y)
the other point (-x, -y) must exist.
If a point is (2, 4), the other point must be (-2, -4)
From the given graphs, the third graph satisfies this condition.
One point is (1, 2), so the other point must be (-1, -2). And this point exists in the graph.
Another point is (3, -1), so the other point must be (-3, 1). And this point also exists in the graph.
The remaining points will satisfy just like the previous two above.
So the answer is the graph in the image shown above.
