Solution:

The direction electric current in Physics taken in the external circuit: from positive to negative terminals of battery, it is the same with direction of electric field. However electrons move from negative to positive terminals. In the question written: emf (E) is taken as. If here means Electromotive Force (EMF), it is scalar quantity, no direction. In this case we may choose answer d-normal.

However, if in the question talking about current direction inside the battery, it is from negative to positive terminals. So, it is also normal.

Note: please provide more details of question if explanation is not enough.
