Solution

The correct option is B $S O_{2}$

$S O_{2}$ reacts with the moisture present in the air and forms sulphuric acid. The sulphuric acid formed comes down along with rainwater and is known as acid rain. The acid rain that falls on the marbles leads to corrosion and yellowing of the marble. Thus yellowing of marble is not caused by $H_{2} S$ , $C O_{2}$ or $N H_{3}$ instead it is caused by $S O_{2}$ .
Hence, option B is correct.
