The Correct Option is D
Solution and Explanation
Concept:
Per capita water demand is the average quantity of water required per person per day.
It is influenced by several factors such as:
• Climatic conditions
• Size of the town
• Quality of water
• Industrial and commercial activities
• Method of water supply
• Metering and charging system Among these, industrial demand has the greatest influence because industries consume large quantities of water.
Step 1: Understand per capita demand. Per capita demand is expressed as \[ \boxed{\text{Litres per capita per day (LPCD)}.} \] The presence of industries significantly increases the total water requirement of a town.
Step 2: Identify the dominant factor. Compared with the other listed factors, industrial demand contributes the maximum increase in water consumption. Hence, \[ \boxed{\text{Industrial demand has the maximum effect on per capita demand}.} \] Therefore, the correct option is \[ \boxed{(D)\;\text{Industrial demand}.} \]
