Solution:The given statement is true.
Concept: The given process includes-
The yellow non-metal feature is the simplest to deduce. Most likely, sulphur should be used. Sulfur is solid and non-metal since it belongs to the p-block of elements.
Therefore, the sulphur should be present in either the greenish-yellow gas or the gas that smells like rotten eggs. We would have encountered a gas that contains sulphur atoms and smells like rotten eggs. It's hydrogen sulphide in this gas.
Consider a gas that is greenish-yellow in colour and that, when combined with hydrogen sulphide, can produce an acidic gas. Chlorine gas should be the greenish-yellow gas. As a result, every gas picked matches the properties listed in the compound.
The reaction's chemical equation is balanced as follows-
Hence, the correct answer is option 1.
