Read the following statements – Assertion (A) and Reason (R). Choose the correct alternative given below:
Assertion (A): World Trade Organization (WTO) is expected to establish the rule-based trading regime, to avoid unilaterally placed arbitrary restrictions by member nations.
Reason (R): It is imperative to enlarge world production and ensure optimum utilization of world resources along with environmental protection.
Assertion (A): The WTO promotes free and fair trade globally, ensuring that trade rules are transparent and consistent to prevent arbitrary trade barriers.
Reason (R): Enlarging world production and optimal resource utilization are aligned with the WTO's goals, including fostering sustainable development.
Linkage: Both statements are true, and Reason (R) explains the broader objectives of Assertion (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 \(P,O,Q\).
