India is described as 'critically deficient' in copper reserves, yet copper remains indispensable to modern industry. What specific properties of copper make it so important, and which industries rely on it most?

Model Answer
Copper is critically important due to three key properties: it is malleable (can be beaten into sheets), ductile (can be drawn into wires), and an excellent conductor of electricity.
These properties make copper indispensable to:
- Electrical industry — manufacturing cables and wires
- Electronics industry — circuit components and equipment
- Chemical industry — industrial machinery and equipment
Despite its importance, India is critically deficient in copper reserves and production, making it a major challenge for these industries.

Explanation
- The examiner expects all three properties (malleable, ductile, good conductor) — missing any one costs marks.
- Name all three industries directly from the textbook: electrical cables, electronics, chemical industries.
- The phrase "critically deficient" from the question echoes the textbook — use it to frame your answer.
- Avoid padding with state-wise mine locations unless specifically asked; stay focused on properties and industries for this question.
