To solve the problem, we need to identify which responsibility among the options is handled by the technical committee after a competition has taken place.
1. Role of the Technical Committee:
The technical committee in sports events is primarily responsible for ensuring smooth conduct of competitions, including technical arrangements before, during, and after the event. Post-competition duties often involve wrapping up and restoring resources used during the event.
2. Evaluating the Options:
- (A) Requisition to purchase equipment: This is a pre-event administrative responsibility, not post-competition.
- (B) Arrangement of equipment and stationery: This is done before or during the competition, not after.
- (C) Arrangement of officials: This is a prior-to-event duty.
- (D) Maintenance of the field: This is a key post-competition responsibility — ensuring the field is restored and maintained after the event ends.
Final Answer:
(D) Maintenance of the field
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 \(P,O,Q\).
