Task: Class Definition Understanding (ontology: Earth_Environment/EnvironmentOntology)

Which of the following definitions best describes 'ionizing radiation'?

A. A radiation process during which electromagnetic waves or their quanta are emitted at wavelengths ranging from millimetre to kilometer scales.
B. An electromagnetic radiation process during which radiant energy with wavelengths in the visible, near-ultraviolet, or near-infrared spectra is realised.
C. A radiation process during which electromagnetic waves or their quanta are emitted at wavelengths between 10 nm and 400 nm.
D. A radiation process during which electromagnetic waves or their quanta are emitted with sufficient energy to disrupt molecular bonds or alter the electron number of atoms.

Answer: A radiation process during which electromagnetic waves or their quanta are emitted with sufficient energy to disrupt molecular bonds or alter the electron number of atoms.
