Which option best describes electromagnetic waves that have enough energy to change atoms or molecules into ions?
A. Waves with low frequency
B. Non-ionizing radiation
C. Waves with long wavelength
D. Ionizing radiation
the answer is
( D ionizing radiation)

UV radiation above 10 eV (wavelength shorter than 125 nm) is considered ionizing.

Explanation:

However, the rest of the UV spectrum from 3.1 eV (400 nm) to 10 eV, although technically non-ionizing, can produce photochemical reactions that are damaging to molecules by means other than simple heat.

its a circle not a square that's simple silly.
