a. 3, 4
b. 2, 5
c. 2, 1
d. 4, 5

ANSWER: 3, 4
 
Since they have their back towards north i.e. they are facing south.

So, the left and right should be taken into consideration accordingly.

If a person is facing South, then, “Person’s Left” will be “Your Right” and vice-versa.

3 is immediate right to 5 i.e. 3, 5
4 is immediately left to 1 i.e. 1, 4

Since, 2 is between 1 and 5, so the sequence becomes 3, 5, 2, 1, 4

3 5 2 1 4

Thus, 3 and 4 are at extreme ends.
