Read the following statements: Assertion (A) and Reason (R). Choose the correct alternative from those given below:
Assertion (A): The maximum value of Marginal Propensity to Save (MPS) can be unity.
Reason (R): At the break-even level of income, savings are zero.
Assertion (A): This is true because theoretically, MPS could reach unity if all additional income is saved, but practically, this is rare.
Reason (R): This is also true since, at the break-even level of income, consumption equals income, leaving savings at zero.
Conclusion: While both statements are true, Reason (R) does not correctly explain Assertion (A) since break-even income concerns savings at zero, not the maximum possible value of MPS.

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 \(P,O,Q\).
