Option 1 : All the statements are needed
1) O is taller than at least one person.
2) N is shorter than at least two person but taller than O.
(N shorter than at least two people but taller than O, who is not the shortest, implies O is the second shortest person and N is the third shortest person.)

3) L is taller than M but shorter than P.
(It is only possible if M is the shortest person and P is the tallest person.)

Clearly, L is the second tallest person and all the three statements are required to answer the question.
