  We study the enhanced production of $\Lambda_c$ charmed baryons relative to
that of charmed $D^0$ mesons in proton-proton collisions at LHC energies. We
simulated collision events with the enhanced color-reconnection model in PYTHIA
8 MC generator and propose measurements based on the comparative use of
different event-activity classifiers to identify the source of the
charmed-baryon enhancement. We demonstrate that in this enhanced
color-reconnection scenario the excess production is primarily linked to the
underlying event and not to the production of high-momentum jets.
