    Answer:

    b) in a direction that makes its potential energy decrease.

    Explanation:

    • As the electric field has the direction that would take a positive test charge under its sole influence, the positive test charge, will have an increase in its kinetic energy.
    • Due to the conservation of energy, in absence of non-conservative forces, this increment must be equal and opposite  to the  change in electric potential energy, which will be always negative, independent of the sign of the charge.
