Yes, the statement is valid. China’s economic transformation is strongly linked to its effective use of Special Economic Zones (SEZs). Introduced in the early 1980s, SEZs became instrumental in integrating China’s economy with the global market. The following arguments justify this:
Attraction of Foreign Investment: SEZs offered relaxed trade regulations, tax incentives, and infrastructural facilities, which attracted massive inflow of Foreign Direct Investment (FDI), thereby boosting capital formation and industrial growth.
Export-led Growth Strategy: These zones were strategically located near coastal areas to promote export-oriented industries. As a result, China emerged as the ‘world's factory’ and experienced a rapid increase in exports and GDP.
Employment Generation and Technological Advancement: SEZs created millions of jobs and facilitated the adoption of modern production techniques, improving productivity and competitiveness.
Pilot for Economic Reforms: SEZs acted as experimental hubs for broader economic reforms. Successful practices within SEZs were later extended across the country.
Thus, the SEZ strategy transformed China from a closed economy to a global manufacturing giant.

Choose the correct answer from the options given below:
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 \(P,O,Q\).
