Motivated by the long-standing tension in the muon anomalous magnetic moment (AMM) and persistent observations of B-physics anomalies in and ratios, we construct a simple two-loop radiative neutrino mass model, and propose a combined explanations of all these apparently disjoint phenomena within this framework. Our proposed model consists of two scalar leptoquarks (LQs), a singlet and a triplet to accommodate and anomalies, respectively. The muon receives chirality-enhanced contribution towards its due to the presence of LQ that accounts for the observed deviation from the Standard Model prediction. Furthermore, we introduce a singlet scalar diquark , which is necessary to break lepton number and generate neutrino mass radiatively with the aid of and LQs. We perform a detailed phenomenological analysis of this set-up and demonstrate its viability by providing benchmark points where a fit to the neutrino oscillation data together with proper explanations of the muon AMM puzzle and flavor anomalies are accomplished while simultaneously meeting all other flavor violation and collider bounds.
