Scientists from the University of New South Wales, in Australia, demonstrated in 2012 that Ohm's Law is valid even for very thin wires, whose cross-sectional area comprises only a few atoms. The table presents the areas and lengths of some of the constructed wires (respectively with the same units of measurement). Consider that resistivity remains constant for all geometries (an approximation confirmed by the study).
| Area | Length | Electrical resistance |
| Wire 1 | 9 | 312 | R1 |
| Wire 2 | 4 | 47 | R2 |
| Wire 3 | 2 | 54 | R3 |
| Wire 4 | 1 | 106 | R4 |
The electrical resistances of the wires, in increasing order, are
(A) $\mathrm{R}1 < \mathrm{R}2 < \mathrm{R}3 < \mathrm{R}4$.
(B) $\mathrm{R}2 < \mathrm{R}1 < \mathrm{R}3 < \mathrm{R}4$.
(C) $\mathrm{R}2 < \mathrm{R}3 < \mathrm{R}1 < \mathrm{R}4$.
(D) $\mathrm{R}4 < \mathrm{R}1 < \mathrm{R}3 < \mathrm{R}2$.
(E) $\mathrm{R}4 < \mathrm{R}3 < \mathrm{R}2 < \mathrm{R}1$.
