People – A, B, C, D, E and F

All are facing north.

1. C is sitting 2^nd to the left of D.

2. Only two person sits between A and B.

3. E is sitting at the extreme left end and neither F nor A is the immediate neighbour of E.

4. B is sitting to the left of A.

As, F and A are not the immediate neighbours of E, Case I is eliminated and the arrangement with the combination of Case II, thus formed is:

Hence, D is at the extreme right end.

The pattern followed is:

There are two series here:

i) 5, 10, 20, 40, 80

5 × 2 = 10

10 × 2 = 20

20 × 2 = 40

40 × 2 = 80

ii) S, R, Q, P, O

S - 1 = R

R - 1 = Q

Q - 1 = P

P - 1 = O

Hence, the correct answer is "80O".
