The state agency responsible for drafting economic policies in Tamil Nadu is the:

The correct answer is the Planning Commission.

The Planning Commission is a state agency responsible for drafting economic policies in Tamil Nadu. It was established in 1956 with the objective of promoting economic development in the state. The Commission is headed by the Chief Minister of Tamil Nadu and its members include representatives from the state government, the private sector, and academia.

The Planning Commission is responsible for formulating the state’s Five Year Plans, which are long-term development plans that outline the state’s economic goals and strategies. The Commission also monitors the implementation of the Five Year Plans and makes recommendations for their improvement.

In addition to the Five Year Plans, the Planning Commission also formulates and implements a number of other economic policies, including industrial policy, agricultural policy, and social welfare policy. The Commission also provides financial assistance to various development projects in the state.

The Planning Commission is an important agency in the economic development of Tamil Nadu. It has played a key role in the state’s economic growth and industrialization. The Commission has also been instrumental in promoting social welfare and improving the quality of life of the people of Tamil Nadu.

The other options are incorrect because they are not state agencies responsible for drafting economic policies in Tamil Nadu.

The State Industries Promotion Corporation of Tamil Nadu (SIPCOT) is a state-owned enterprise that promotes industrial development in Tamil Nadu. It provides land, infrastructure, and other facilities to industries.

The Commercial Taxes Department is responsible for collecting taxes on goods and services sold in Tamil Nadu.
