Explanation:

- There are six people: Ali, Parth, Roy, Minal, Sudhir, and Zeeshan.

- They are sitting in a straight row, all facing north.

- Sudhir and Zeeshan are in the center, so they occupy the 3rd and 4th positions.

- Ali and Parth are at the corners, meaning Ali is at one end, and Parth is at the other.

- Roy is immediately left of Ali. So, if Ali is at one end, Roy must be next to Ali.

- Based on this arrangement, Ali is either at position 1 or 6. If Ali is at 1, Roy is at 2. Thus, Parth is at 6.

- Therefore, the order from left to right is: Ali, Roy, Sudhir, Zeeshan, Minal, Parth.

- Minal is immediately to the right of Parth.

Hence, the correct answer is:

Option 4: Minal
