In winding number method , constructed horizontal line between point Q and point P intersects two edges of the polygon with winding no. +1 and -1. Tell whether point Q is inside or outside and what is the net winding ? Note : Q is the point to be tested for inside test.P is point outside the polygon.

• A. outside , zero
• B. inside , zero
• C. outside , nonzero
• D. inside , nonzero
