Direction: Study the given information carefully and answer the question that follows:
(i) A, B, C, D, E, F and G are sitting on a wall and all of them are facing east.
(ii) C is on the immediate right of D.
(iii) B is at an extreme end and has E as his neighbour.
(iv) G is between E and F.
(v) D is sitting third from the south end.

Which of the conditions (i) to (v) given above is not required to find out the place in which A is sitting?

Following the step-by-step logic to deduce the arrangement from positions $1$ to $7$ (North to South):
* From (v), D is at $5$.
* From (ii), C is at $6$.
* From (iii), B is at $1$ and E is at $2$.
* From (iv), G is at $3$ and F is at $4$.
* Finally, by elimination, the only empty place left is $7$, which belongs to A.
* Condition (i) establishes the direction framework (East, left-right parameters).
Since every single piece of information is explicitly utilized to fill out unique positions and eliminate alternative spots, all conditions are required.
