(A) Erythropoietin: Therapeutic Use: Erythropoietin is primarily used for the treatment of anemia, especially in patients with kidney disease and those undergoing chemotherapy. Animal Cell Line: The most commonly used animal cell line for production of Erythropoietin is CHO (Chinese Hamster Ovary) cell line.
(B) Herceptin: Therapeutic Use: Herceptin (Trastuzumab) is used for breast cancer therapy, particularly in cases where the cancer cells overexpress the HER2 protein. Animal Cell Line: The production of Herceptin typically involves the CHO cell line.
(C) Interleukin-2: Therapeutic Use: Interleukin-2 is mainly used for treating cancer. Animal Cell Line: The most used cell line for production of Interleukin-2 is CHO cells.
(D) Tissue plasminogen activator (tPA): Therapeutic Use: Tissue plasminogen activator (tPA) is used in treating stroke and dissolves blood clots. Animal Cell Line: tPA is produced using CHO cells.
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 \(P,O,Q\).
