Explanation:

Let’s break it down one step at a time:

- We’ve got five friends in a line, all facing north.

- Mohit is second to the left of Arjun. So the order is: Mohit _ _ Arjun _ (or some similar positions, but Mohit must be two spots left of Arjun).

- Harman is immediately to the right of Mohit. So Harman sits next to Mohit’s right side.

- Surya is immediately to the left of Kartik. So Surya and Kartik are together, Surya on Kartik’s left.

- There are two people between Surya and Mohit. So there’s a gap of exactly two seats between these two.

If you sketch this out:

- Let’s say positions: 1 2 3 4 5 (left to right).

- Place Mohit at position 2 ? Mohit _ _ Arjun _

But Harman must be immediately right of Mohit: so that's Mohit Harman ...

- Surya and Kartik are together somewhere; Surya to Kartik's left.

- If there are two people between Surya and Mohit, the only way this fits is:

Surya _ _ Mohit Harman Kartik (but that's six people).

- Try position 1 as Mohit: Mohit Harman _ _ _

- Mohit must be second to the left of Arjun, so Arjun is at position 3.

So: Mohit Harman Arjun _ _

- Only Kartik and Surya left. Surya must be left of Kartik, so positions 4 and 5: Surya Kartik

- Now, check if Surya and Mohit have two people between them: Mohit (1), Harman (2), Arjun (3), Surya (4), Kartik (5). Two people between Surya (4) and Mohit (1): Harman and Arjun. That fits.

So the final order: Mohit, Harman, Arjun, Surya, Kartik

Corners: Mohit (1) and Kartik (5)

So, here’s what all that means:

- Option 1: Mohit and Kartik – This matches the solution!

- Option 2: Arjun and Kartik – No, Arjun is in the middle.

- Option 3: Mohit and Arjun – They aren't both at the corners.

- Option 4: Harman and Kartik – Harman sits next to Mohit, not at a corner.
