ODP stands for which term related to refrigerants?

ODP stands for ozone depletion potential. It’s a relative index used to compare how much a substance can contribute to the destruction of the stratospheric ozone layer, using CFC-11 as the reference with a value of 1.0. Substances with lower ODP have less ozone-depleting impact; many modern refrigerants (like most HFCs) have ODP around zero, while some HCFCs have small positive values. The ozone-destroying effect comes from halogen radicals released in the upper atmosphere, which catalytically destroy ozone molecules. This concept is different from climate-related measures like global warming potential. The other terms listed aren’t standard or accurate descriptors for this concept.
