<em>The correct option is B) the availability of money</em>
Explanation:
Potable water can be described as the water which is safe to drink. Nowadays, with the rapid industrialization progress, it is important to process water so that it can be used for human consumption. The processing of water to make it clean enough requires money. The more money a community will have, the more machinery and plants it will be able to set up for the processing of water.

Lactose is more likely to be utilised by E. Coli than Arabinose because Lactose will yield more energy (ATP) and lactose breakdown will give glucose and galactose and these will enter into the glycolytic pathways to pyruvate for ATP generation until Arabinose which will undergo Pentose phosphate pathway and this does not produce enough energy.
