Explicit solutions of the WDVV equation determined by the "flat"   hydrodynamic reductions of the Egorov hydrodynamic chains
  Classification of the Egorov hydrodynamic chain and corresponding 2+1 quasilinear system is given in the previous paper. In this paper we present a general construction of explicit solutions for the WDVV equation associated with Hamiltonian hydrodynamic reductions of these Egorov hydrodynamic chains
