CorrectNot quiteAnswer D

Correct answer: D

Explanation

  1. Parul > Lalit > Mansi > Ojas, and Neeraj > Mansi, so Neeraj may be 1st, 2nd or 3rd.

  2. 'Neeraj scored more than Parul' leaves only Neeraj > Parul > Lalit > Mansi > Ojas: one order.

  3. 'Neeraj scored less than Parul' still leaves Neeraj above or below Lalit: two orders.

  4. 'Ojas scored the least' and 'Lalit scored more than Ojas' are already known, so three orders remain.

Worth noting

A clue that is already implied adds nothing. Test each extra clue by counting how many orders survive; the right one leaves exactly one.
