Sanjay's occupational immobility stems from skill mismatch

Steps:

• Define occupational immobility as the difficulty in switching to a new job due to lack of transferable skills.
• Identify the scenario: The mine closure eliminates Sanjay's specific coal mining role, leaving no similar jobs.
• Note his desire to stay in the village, implying local jobs exist but require different skills.
• Conclude the barrier is his mining-specific expertise not applying elsewhere, causing immobility.

Why B is correct:

• Occupational immobility occurs when workers lack skills relevant to alternative jobs, per labor economics, preventing Sanjay from transitioning despite unemployment.

Why the others are wrong:

• A: Reflects geographical immobility from personal ties, not skill-based job switching.
• C: Involves geographical costs of relocation, unrelated to occupational skill barriers.
• D: Pertains to geographical housing affordability, not skill deficiencies for new roles.

Final answer: B
