Answer 1

The correct answer is (b) Ratio of flux lines crossing a surface and the surface area To explain I would say: Electric flux density is given by the ratio between number of flux lines crossing a surface normal to the lines and the surface area. The direction of D at a point is the direction of the flux lines at that point.
