Five cylindrical wires are made of the same material. Their lengths and radii are: Wire 1: length e, radius r. Wire 2: length 14, radius r/2. Wire 3: length /2, radius r/2. Wire 4: length e, radius r/2. Wire 5: length 56, radius 2r Rank the wires according to their resistances, from least to greatest. (A) 1, 2, 3, 4, 5. (В) 1, 2, 4, 3, 5. (C) 1, 3, 4, 2, 5. (D) 5, 4, 3, 2, 1. (E) 1 and 2 tie, then 5, 3, 4.
