Answer 1

The correct option is D (d) All of the above

One of the primary components of photochemical smog is ozone.
While ozone in the stratosphere protects earth from harmful UV radiation, ozone on the ground is hazardous to human health.
Ground-level ozone is formed when vehicle emissions containing nitrogen oxides (primarily from vehicle exhaust) and volatile organic compounds (from paints, solvents, printing inks, petroleum products, vehicles, etc.) interact in the presence of sunlight
