Money supply is a stock concept measured at a specific point in time, not over a period of time, making statement (i) incorrect.
Statement (ii) is incorrect because the government’s stock of money is not included in money supply.
Statement (iii) is also incorrect as money supply includes currency held by the public, not with the Central Bank.
Since all three statements are incorrect, the correct answer is (D) (i), (ii), and (iii).
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 \(P,O,Q\).
