Assertion (A): The expression "HELLO".sort() in Python will give an error.
Reason (R): sort() does not exist as a method/function for strings in Python.
Mark the correct choice:
The sort() method is not defined for string objects in Python. It is used for lists, not strings. Therefore, trying to use sort() on a string object like "HELLO" results in an AttributeError, making both the assertion and reasoning true, with (R) correctly explaining (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 \(P,O,Q\).
