Explanation:

Let’s break down the seating arrangement step by step:

- There are 7 friends sitting in a row: K, L, M, N, O, P, Q.

- All are facing north, so left means their left.

- K is sitting exactly in the middle, so K is at position 4.

- K is immediately left of O, so O is at position 5.

- L is third to the right of K (positions 4 ? 5 ? 6 ? 7), so L is at position 7.

- M and Q are not at the extreme ends, so neither at position 1 nor 7.

- Only P is between Q and N, so Q-P-N or N-P-Q are possible.

Placing above clues:

- K at 4, O at 5, L at 7.

- Now, M and Q cannot be at 1 or 7. Only positions left for M and Q are 2, 3, 6.

- Let’s try Q at 6, meaning P could only be at 5 or 7, which are not possible.

- Try Q at 2, P has to be at 3 or 1, but 1 is not allowed for Q, so this fails.

- Try Q at 3, P must be at 2 or 4, but 4 is K.

- Now try Q at 6, P at 5 or 7 (not possible).

Let’s put P at 3, which means Q and N take 2 and 1 (since only P is between them).

That means:

1: N

2: Q

3: P

4: K

5: O

6: M

7: L

So, N is sitting at the extreme left end.

- O is at 5, not at the left end.

- Q is at 2.

- N is at 1 (leftmost).

- L is at 7 (rightmost).

Correct Answer:

- Option:3, N

Here’s a summary:

- N is at extreme left end (position 1).

- K is in the middle (4).

- O is immediately right of K (5).

- L is third to right of K (7).

- Q and M are not at the ends.

- Only P is between Q and N.

So, N (option 3) is correct.
