Option 4 :

**Option (1):**

- Here the current is flowing in the direction of Electromotive Force (Voltage).
- Since the Value of Resistance is not given hence Ohms law cannot be formed.

**Option (2):**

- Here the current is flowing in the opposite direction of Electromotive Force (Voltage).
- Since the Value of Resistance is not given hence Ohms law cannot be formed.

**Option (3):**

It can be drawn as,

Apply Ohms law,

**V = IR**

**Option (4):**

It can be drawn as,

Apply Ohms law,

**- V = - IR**

**Hence, correct option is (4).**
