Following are the industry categories classified under the Industrial Policy Resolution 1956, EXCEPT:

Correct option is A

The correct answer is (a) industries in the cooperative sector.
The Industrial Policy Resolution of 1956 in India outlined specific categories for industrial development, focusing on the role of the state and the private sector.
 (a) Industries in the cooperative sector: This option is not mentioned in the 1956 policy. The resolution primarily targeted state involvement and private sector participation in strategic and important industries. It did not explicitly categorize industries under the cooperative sector, making it the correct answer as it is not classified under the policy.
 (b) Industries with public sector taking the lead and the private sector playing a supplementary role: This is aligned with the categorization under the policy, where the state was envisioned to lead in key industries with the private sector supplementing.
 (c) Industries in the private sector: Certain industries were designated to be primarily under private sector control, particularly those not listed as strategic or essential.
 (d) Industries with exclusive ownership of the state: Reflects the first schedule of the resolution, which specified industries critical to national interest that were to be exclusively owned and managed by the state.
Thus, the answer to the question is: (a) industries in the cooperative sector. This category was not explicitly defined under the Industrial Policy Resolution 1956.
