Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). In the light of the above statements, choose the most appropriate answer from the options given below.
Assertion (A):PM10 is preferred over Total Suspended Particles (TSP) for air quality monitoring studies.
Reason (R):Particles larger than 10 micron are a better indicator of the potential health effects of particulate air pollution.
ABoth A and R are correct and R is the correct explanation of A
BBoth A and R are correct but R is not the correct explanation of A
CA is correct but R is not correct ✓ Correct
DA is not correct but R is correct
Correct answer: (C) A is correct but R is not correct
Explanation
The assertion is correct: PM10 is preferred over total suspended particles for air quality monitoring.
The reason is incorrect: smaller particles below 10 micron, not larger ones, better indicate health effects.
Fine particles penetrate deep into the lungs, making them the key concern.
Larger particles are mostly filtered by the nose and upper airways.
A true assertion pairs with a false reason here.
PM10 refers to particulate matter with diameter up to ten micrometres.
