It is given that only Abhishek
(A) and Bineeta(B) face away from the centre, which implies Manisha(M), Hari(H), Vaishali(V), and Gaurav(G) face the centre. (point 2)
Gourav is on the immediate left of Bineeta (Bineeta faces away from the centre). (point 1)
There are two people between Gourav and Hari ( both are facing inwards) (point 4)
It is given that Abhishek is the neighbour of both Manisha and Gourav, which implies Abhishek sits between Manisha and Gourav. Vaishali and Hari seats adjacent to each other.
The final diagram:
After Hari interchanges his position with Abhishek (having the same direction), the diagram will look like:
From the diagram, we can see that Vaishali sits to the left of Abhishek. The correct answer is A.
