Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A mixture of nitrogen and carbon dioxide can be distinguished by passing it through lime water. Because Nitrogen does not turn lime water milky and Carbon-di-oxide forms carbonate with lime which makes lime water milky.
From this experiment we can distinguish nitrogen and carbon-di-oxide. Hence, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
