The correct answer is option 4: R3 > R2 > R1.
In the given graph, we can see that for resistor 3, the slope of the line (change in V/change in I) is steeper compared to resistor 2, and resistor 2 has a steeper slope compared to resistor 1.
The slope of the current-voltage graph is inversely proportional to the resistance of the resistor. Higher resistance results in a steeper slope and vice versa.
Therefore, we can conclude that resistor 3 has the highest resistance (R3), followed by resistor 2 (R2), and resistor 1 (R1) has the lowest resistance among the three.
Hence, option 4 is correct: R3 > R2 > R1.
This means that the resistance values decrease from resistor 3 to resistor 1.
