- Statement I is true as collective farming is based on social ownership and collective labour, where land and resources are shared among farmers.
- Statement II is correct because collective farming was introduced in the Soviet Union, primarily in the form of collective farms.
- Statement III is incorrect, as in a collective farm, farmers typically share inputs and outputs equally, irrespective of their individual land sizes.
- Statement IV is correct as this type of collective farming is indeed called 'Kolkhoz' in the Soviet Union.
Thus, the correct option is (A).
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
