The representation of Nevanlinna Pick Problem is well known, see [7], [8] and [11].The aim of this paper is to find the necessary and sufficient condition for the solution of NevanlinnaPick Problem and to show that there is a one-to-one correspondence between the solutions of theNevanlinna Pick Problem and the minimal selfadjoint extensions of symmetric linear relation inHilbert space. Finally, we define the resolvent matrix which gives the solutions of the NevanlinnaPick Problem
