Observe the schematic representation of assisted reproductive technology given below:

Identify the most appropriate technique depicted in the above diagram.
Step 1: Understanding ICSI.
- The diagram represents Intracytoplasmic Sperm Injection (ICSI).
- In this technique, a single sperm is directly injected into the cytoplasm of an egg using a fine needle.
Step 2: Use of ICSI. - ICSI is used in cases of male infertility, such as low sperm count or motility.
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 \(P,O,Q\).
