D/H ratios measured from DCO⁺, DNC, DCN, and CH₂DOH towards the Clump (dashed black lines and grey shadows) compared with literature values across low-mass starless and pre-stellar cores and low-mass protostars, high-mass IR-dark clumps, high-mass protostellar objects, and comets. For reference, we report the cosmic D/H ratio (dotted-dashed black line; Oliveira et al. 2003) and the D/H measured in meteorites (red shadow) and proto-solar nebula (dotted cyan line).
