Which of the following statements about control of air pollution are correct?

AA catalytic converter oxidises CO to $CO X_{2}$ .
BTrees such as Pinus and Quercus can metabolise nitrogen oxide.
CA limestone slurry scrubber can remove $SO X_{2}$ from flue gas.
DAn electrostatic precipitator removes gaseous $NO$ from vehicle exhaust.

Answer: A, B, C

Plantation of trees that metabolise

NOx

, scrubbing with

CaCO X_{3}

slurry and oxidation of CO over Pt/Pd are standard measures. An electrostatic precipitator collects charged particulates only and does not remove gases.
