Option 2 : Chetna

Six people: Amit, Beena, Chetna, David, Emran, Farah

1) Neither Amit nor Beena sits at any of the ends.

2) Farah sits immediately next to the person sitting at the right end of the line.

3) Amit is sitting second to the right of the person sitting at the left end.

4) David sits at one of the ends but is not an immediate neighbour of Farah.

(Thus, David cannot sit at the right end, hence David sits at the left end)

5) Beena does not sit between David and Amit.

(Therefore, Beena should sit between Amit and Farah)

6) Chetna is not an immediate neighbour of David or Amit.

(Therefore, Chetna sits at the right end and Emran sits between David and Amit because only he is left)

This is the final seating arrangement.

Hence, Chetna sits at the extreme right end.
