  We present theoretical model comparison with published ALICE results for
D-mesons (D$^0$, D$^+$ and D$^{*+}$) in $p$+$p$ collisions at $\sqrt{s}$ = 7
TeV and $p$+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV. Event generator
HIJING, transport calculation of AMPT and calculations from NLO(MNR) and FONLL
have been used for this study. We found that HIJING and AMPT model predictions
are matching with published D-meson cross-sections in $p$+$p$ collisions, while
both under-predict the same in $p$+Pb collisions. Attempts were made to explain
the $R_{pPb}$ data using NLO-pQCD(MNR), FONLL and other above mentioned models.
