b. 5.0-micrometer
c. 10.0-micrometer
d. 7.5 micrometre
Answers (1)
The Central Pollution Control Board (CPCB) states that the most dangerous particles for human health are those that have a diameter of 2.5 micrometres or smaller. PM2.5, or fine particles, is the name given to these particles. They can cause respiratory issues and possibly death if they are inhaled deeply into the lungs and respiratory tract. Hence, (a) is the correct option.
