Several wires of the same fixed length are made of metal of constant resistivity. The wires have different cross-sectional areas. Which graph represents the variation of the resistance R of the wires with their cross-sectional area A?

1. Agraph A: R decreasing linearly with A
2. Bgraph B: R decreasing as inverse of A
3. Cgraph C: R increasing linearly with A
4. Dgraph D: R increasing non-linearly with A
