• D. Nitrogen oxide

Answer 1

The correct option is C Ozone

Ozone is a toxic gas which causes severe effects on the body on inhalation. The gas causes irritation in the nose, throat and other parts of the respiratory system. Inhalation of about 0.1 ppm of the gas may result in effects like swelling and bleeding of the lungs. Haemorrhage of the lungs, stomach and intestine is a common effect of the ozone breathing.

Thus, the correct answer is option C.
