The Employees’ State Insurance Scheme provides Social Security coverage in India to workers employed in certain sectors if conditions of the Employees State Insurance (ESI) Act are met.

Option 1, includes Hotels and restaurants, Motor transport undertakings, and Newspaper establishments, which are indeed covered under the Social Security scheme. However, it excludes Private medical institutions which are also covered, making this option incorrect.

Option 2, suggests that Only Motor transport undertakings are covered under this scheme which is incorrect because the other sectors are also covered.

Option 3, includes Hotels and restaurants, and Newspaper establishments, but excludes Motor transport undertakings and Private medical institutions. This makes it incorrect because all these sectors are covered.

Option 4, correctly includes all four sectors: Hotels and restaurants, Motor transport undertakings, Newspaper establishments, and Private medical institutions, and is thus the correct answer as these sectors have the ‘Social Security’ coverage under the Employees’ State Insurance Scheme.
