Number of electric lines of force passing throug a certain area is known as:

Explanation

SHOULD be B)A: An electric field is defined as any region around a charge in which an electric test charge would experience an electric force B: Electric Flux is the measure of the number of lines of force that pass through an area in an electric field.C: The intensity of an electric field at any point is the force per unit positive test charge placed at a pointD: Gravitational field is the field of force surrounding a body of finite mass in which another body would experience an attractive force that is proportional to the product of the masses and inversely proportional to the square of the distance between them
