Question

select the correct answer from the drop-down menu.
the intensification of ultraviolet rays has contributed to
options:
an increase in skin cancer
a decrease in clean water
an increase in chlorofluorocarbons

Ultraviolet (UV) rays damage DNA in skin cells, increasing mutation risk and skin cancer incidence. Clean water decrease is unrelated to UV intensity, and chlorofluorocarbons cause ozone depletion (which increases UV rays, not the reverse).

Answer:

an increase in skin cancer
