A metal rod of length 10 {\cm} and a rectangular cross-section of 1 {\cm}^{'} \times \frac{1}{2} {\cm} is connected to a battery across opposite faces. The resistance will be

Correct Answer is : Maximum when battery is connected across 1cm×12cm faces

Maximum when the battery is connected across 10 {\cm} \times 1 {\cm}.

Maximum when battery is connected across 1 {\cm} \times \frac{1}{2} {\cm} faces

Maximum when the battery is connected across 10 {\cm} \times \frac{1}{2} {\cm}

Same irrespective of three faces
