The correct option is Strong dependence on bulky raw materials.
Explanation
Footloose industries are a specific class of manufacturing or service industries that are not tied to any specific location based on the availability of raw materials or markets. Their location is largely independent of the weight or bulk of resources, allowing them to be established in diverse geographical areas.
Detailed Analysis:
- Strong dependence on bulky raw materials is the correct answer (as the exception): Footloose industries do not depend on bulky or weight-losing raw materials. Industries that rely on heavy raw materials (like Iron and Steel or Cement) must be located near the source of materials to reduce transport costs. Footloose industries, by contrast, typically process small, light, or high-value components.
- Use of light raw materials is a characteristic: These industries generally utilize light raw materials or component parts (e.g., computer chips, diamonds, precision instruments) where transportation costs are a negligible fraction of the total cost.
- Ability to locate in diverse areas is a characteristic: Because they are not resource-bound, these industries have the flexibility to locate in a wide range of areas, often preferring locations with good accessibility, pleasant environments, or proximity to similar firms (agglomeration economies).
- Requirement of skilled labour is a characteristic: Footloose industries often involve high-tech manufacturing or precision engineering (e.g., electronics, watchmaking), which requires a highly skilled workforce rather than large amounts of unskilled manual labor.
Key Takeaway:
The defining feature of a footloose industry is its spatial flexibility; it is not restricted by the location of raw materials or markets, unlike weight-losing industries which are material-oriented.
