The highly quantum\u2010confined nanorods exhibit exceptionally large lattice strain nearly an order of magnitude higher than in previously reported systems which acts as the primary driving force for breaking local inversion symmetry. This strain\u2010mediated symmetry breaking gives rise to strong circular dichroism (CD), natural circular dichroism (NCD), and robust polarization\u2010dependent photoluminescence (PL), all persisting up to room temperature. Piezoresponse force microscopy confirms local ferroelectricity, magnetization measurement showed diamagnetic to superparamagnetic transition while magneto\u2010optical measurements reveal nonlinear Zeeman response and zero\u2010field magnetic signatures linked to the asymmetric chiral potential. Collectively, these results establish strain as a powerful route for inducing chirality, ferroelectricity, and magneto\u2010optical coupling in achiral inorganic lattices, opening new pathways for chiral optoelectronics and spin\u2010selective devices.\n
