The resistance of the wires can differ due to length and cross sectional area.

Explanation:

As we all know that the resistance depends on length, cross sectional area and resistivity. It's formula is :

R = рL/A

If we increase the length of one wire then obviously there will be an increase in it's resistance. So the longer wire will have the greater resistance. Similarly upon increasing the cross sectional area of a wire its resistance decrease. So these are the two factors on the basis of which resistance of wires can differ.

     As far as resistivity is concerned, its purely a material property. It depends on the material of wire. As in this case both wires are made up of same material that is copper so it does not made them different from each other. Applied voltage is same for both of the wires so the electric current will be the same for both of these wires.

The correct options are length and the cross sectional area.
