Solution
Both A and R are true, but R is not the correct reason for А.
Explanation:
A is true because burning garbage (often under limited oxygen/smouldering conditions) produces carbon monoxide, an extremely harmful gas, and the sources explicitly note CO formation from incomplete burning. R is true because people burn refuse because it is quick and cheap. However, R does not explain why CO is formed: the chemical cause is incomplete combustion (insufficient oxygen/low-temperature burning), not the fact that burning is cheap.
