Option 2, which is "Agriculture Growth Rate of 5 per cent," is NOT a target of the 12th Five-Year Plan.

The 12th Five-Year Plan is a government initiative in India that outlines the country`s economic and social goals for a five-year period. It focuses on various sectors like agriculture, manufacturing, infrastructure, and environment.

Option 1, "Real GDP Growth Rate of 8 per cent," is a target of the plan. This means that the government aims for the economy to grow at a rate of 8% during the plan period.

Option 3, "Manufacturing Growth Rate of 10 per cent," is also a target. It signifies the government`s goal to boost the manufacturing sector and increase its growth by 10% during the plan period.

Option 4, "Increase in green cover by 1 million hectare every year during the Plan period," is another target of the plan. It highlights the government`s commitment to environmental conservation and aims to expand the green cover by 1 million hectares each year.

In summary, option 2, "Agriculture Growth Rate of 5 per cent," is the correct answer as it is NOT a target of the 12th Five-Year Plan.
