Except for seats numbered 2 or 4 all other seats numbered 1,3,5,6 will have to be occupied.
Yasin will have to sit at seat number 1, as this seat will have to remain occupied in all sitting arrangements as no other person has this option.

Rehman will have to sit only at seat number 6, as this seat will have to remain occupied in all sitting arrangements and no other person has this option.

When Rehman sit on Seat no. 6, then Ali will have to sit only on Seat No. 5 as Arafat and Rasheed do not have this option.

Seat No. 4 can remain unoccupied in following 2 ways. ( name - seat no.)
(1): Yasir-1; Arafat-2; Rasheed-3; Ali-5; Rehman-6; Unoccupied-4
(2): Yasir-1; Arafat-3; Rasheed-2; Ali-5; Rehman-6; Unoccupied-4
