A D-parity violated SUSY SU(4) x SU(2) L x SU(2)ᵣ gauge model with the Higgs sector 2(4,1,2)+(4-bar,1, 2)+(1,2,2)+some(1,1,1)'s is shown to have the following advantages: (i) It is the simplest and almost unique solution that satisfies Mₓ = Mstring 0.6 x 10¹⁸ GeV and MINT 5 x10¹¹ GeV in superstring derived SUSY SO(10) GUTs. (ii) The proton is stable enough by the automatic "doublet-triplet splitting" closely connected with the D-parity violation. (iii) The minimization of SUSY one-loop effective potential in a toy model suggests that the SO(10) gauge theory tends to break dynamically down to the SU(4) x SU(2) L x SU(2)ᵣ model.
