The right answer is false.
The harmful effects of ground-level ozone on living beings are numerous: tingling of the eyes, cough, difficulties to breathe, migraines, weakening of the immune system, etc.
Stratospheric ozone strongly absorbs UV rays from the sun, without which these rays will not be filtered.
Exposure to ultraviolet radiation can cause several types of skin cancer in humans the most common are: malignant, basal cell carcinoma and squamous cell cancer. They are also dangerous on the eyes as they can cause eye diseases such as cataracts and photokeratitis.
The rays (UV) are also dangerous on the immune system because they can weaken the response of the immune system and also causes its alteration.
Based on this comparison, we can conclude that depletion of stratospheric ozone is more dangerous.
