Expert Answer:

1) The graph is of current vs potential difference. So, the slope of the graph gives 1/R.
 
2) Hence, the resistance from the graph can be found by 1/slope. Therefore, we can infer that if a graph has higher slope, then that conductor will have smaller resistance.
 
3) From the graph, B has higher slope than A. Therefore, A will have higher resistance than B.
