  In this work, the relative Underlying Event (UE) transverse multiplicity
activity classifier ($R_{\rm {T}}$) is used to study the strange and
multi-strange hadron production in proton-proton collisions. Our study with
$R_{\rm {T}}$ would allow to disentangle these particles, which are originating
from the soft and hard QCD processes. We have used the PYTHIA 8 Monte-Carlo
(MC) with a different implementation of color reconnection and rope
hadronization models to demonstrate the proton-proton collisions data at
$\sqrt{s}$ = 13 TeV. The relative production of strange and multi-strange
hadrons are discussed extensively in low and high transverse activity regions.
In this contribution, the relative strange hadron production is enhanced with
increasing $R_{\rm {T}}$. This enhancement is significant for the strange
baryons as compared to mesons. In addition, the particle ratios as a function
of $R_{\rm {T}}$ confirm the baryon enhancement in new Color Reconnection
(newCR), whereas the Rope model confirms the baryon enhancement only with
strange quark content. Experimental confirmation of such results will provide
more insight into the soft physics in the transverse region, which will be
useful to investigate various tunes based on hadronization and color
reconnection schemes.
