How do electric field lines indicate the strength of the field? a) by how long the lines are b) by how close the lines are c) by the direction the lines are pointing d) by showing the charge that creates the lines

I am almost sure it it (c)

The correct answer is the option B which is by how close the lines are.

Explanation:Electric field of lines are a type of pattern used to describe the direction and the strength of the electric field.These are lines which always projects from Positive ions to negative ions.Then strength of electric field is shown by the closeness of lines.Where these lines are close to each other it means strength of electric field is high and vice versa.These lines show that electric field is a vector property.
