Multiple Choice

The lowest ozone depletion potential (ODP) value is 1.

Explanation:
ODP is a relative measure used to compare how much a substance can deplete stratospheric ozone, with CFC-11 assigned a value of 1. Substances that do not deplete ozone at all have an ODP of 0, so the lowest possible ODP value is 0, not 1. The statement incorrectly implies the minimum is 1, which isn’t true because some substances have no ozone-depleting potential at all.
