Consider the following statements regarding Industrial Corridors in India:

1. They are linear development zones.

2. They connect all major State capitals through an integrated network of roads, railways, ports and airports.

3. They promote acceleration of industrial growth.

Which of the statements given above is/are correct?

Statement 1 is correct — industrial corridors are linear development zones built along dedicated transport/infrastructure spines. Statement 3 is correct — their core purpose is to accelerate industrial growth by co-locating manufacturing with logistics infrastructure. Statement 2 is incorrect — corridors like DMIC connect specific industrial nodes along a chosen route, not "all major State capitals" via a nationwide integrated network. Hence only 1 and 3 are correct.
