Show answer & explanation
Correct answer: C
Key idea: place people step by step using the given adjacency and left/right constraints (facing the centre means a person's left is the clockwise neighbour).
Place Rashmi at any seat (call it position 0).
Deepa is to the left of Rashmi. Facing the centre, left is the clockwise neighbour, so put Deepa at position 1 (clockwise from Rashmi).
Kamla is between Tanu and Deepa, so Kamla must be the other neighbour of Deepa (position 2). Then Tanu is the neighbour on the other side of Kamla (position 3).
Vimla and Tanu are neighbours, so place Vimla at position 4 (the remaining neighbour of Tanu).
The remaining person, Priya, goes to position 5.
Seating (positions numbered clockwise): 0 = Rashmi, 1 = Deepa, 2 = Kamla, 3 = Tanu, 4 = Vimla, 5 = Priya
Since opposite seats in a hexagon are three positions apart, Kamla at position 2 is opposite position 5, which is Priya.
Answer: Priya.
