Step-by-step explanation:
A charge alters the space around it. This alteration of space is called the electric field. It is also defined as the electric force acting on a charged particle per unit test charge. It is given by :
![E=(F)/(q)](https://img.qammunity.org/2020/formulas/physics/middle-school/rd627zvztvryx8r63bpbbe8cpfd3t3gkl0.png)
Where
F is the electric force,
![F=(kq_1q_2)/(r^2)](https://img.qammunity.org/2020/formulas/physics/college/elnujrr1nnn9e7a8ua0cruv46o2bidzxsk.png)
The direction of electric field is in the direction of electric force. For a positive charge, the direction of electric field lines are outwards and for a negative charge, the direction of field lines are inwards.
Hence, the correct option is (c) "electric field".
