Anegative test charge experiences a force to the right as a result of an electric field. which is the best conclusion to draw based on this description?

the electric field points to the left because the force on a negative charge is opposite to the direction of the field.
the electric field points to the right because the force on a negative charge is in the same direction as the field.
no conclusion can be drawn because the sign of the charge creating the field is unknown.
no conclusion can be drawn because the amount of charge on the test charge is unknown.

The correct choice is

The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Reason :

In an electric field, a positive charge has tendency to move from high to low potential and hence experience the electric force in the direction of electric field since electric field lines are directed from high to low potential.

In an electric field, a negative charge has tendency to move from low to high potential and hence experience the electric force in the direction opposite to  electric field since electric field lines are directed from high to low potential.

So it's option A

The electric field points to the left because the force on a negative charge is opposite to the direction of the field.
