Solution
Both A and R are true but R is not the correct explanation of A.

Diesel vehicles release suspended particulate matter (SPM) as an important air pollutant. Therefore, Assertion (A) is true.
Catalytic converters help to reduce harmful emissions from automobiles. Therefore, Reason (R) is true.
However, the reason does not explain why diesel vehicles release SPM.
Hence, both A and R are true but R is not the correct explanation of A.
