A negative 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?

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