C. a and b

D. a or b

Respuesta :

Answer: A and B

Explanation:

An electric field develops around a charge. The electric field lines represent the region in space where a positive test charge experiences an electric force. A electric force exists between  the two charges.

Thus, when charges build up on a surface, they apply force to charges wandering nearby and also create electric field. So, correct option is Both A and B.
