Soot particles released from a coal-based thermal power plant are most likely to cause health problems related to which body system?
ADigestive system
BRespiratory system
CSkeletal system
DReproductive system
Answer & Solution
Correct answer: B. Respiratory system
1. Burning of coal releases soot particles into the environment.
2. These fine particles are breathed in through the air.
3. They cause serious problems of the respiratory system, such as asthma.
4. Soot is inhaled, not eaten, so the digestive system (option A) is ruled out.
