Electric flux density in electric field is referred to as

A)
Number of flux lines
B)
Flux lines per unit area
C)
Direction of flux at a point
D)
Ratio of flux lines crossing a surface and the surface area

Correct Answer : Option (D) :   Ratio of flux lines crossing a surface and the surface area

Explanation : 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.
