d. all of the above

Explanation: Stratospheric ozone absorbs harmful UV radiation (protecting life at the surface), its UV absorption heats the stratosphere and thus helps maintain the atmosphere’s temperature structure, and by blocking UV it also reduces the amount of radiation that drives photochemical ozone formation in the lower (tropospheric) air.
