Explanation:

- Option 1: Make India exporter of raw material

- This was indeed a motive. The colonial powers sought to extract and export raw materials from India to fuel their own industrial needs.

- Option 2: Make India importer of finished goods

- This was also a motive. By turning India into a market for finished goods, colonial powers could sell their industrial products and suppress local industries.

- Option 3: Both (a) and (b)

- This option is correct. Both exporting raw materials and importing finished goods were key motives behind deindustrialization.

- Option 4: None of the above

- This is incorrect because the first two options are valid motives.
