190071 Given below are two statements, one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\)Assertion \(A :\)- Carbon forms two important oxides \(- CO\) and \(CO _2 . CO\) is neutral whereas \(CO _2\) is acidic in nature.Reason \(R :\)- \(CO _2\) can combine with water in a limited way to form carbonic acid, while \(CO\) is sparingly soluble in water.In the light of the above statements, choose the most appropriate answer from the options given below :-

1 Both \(A\) and \(R\) are correct but \(R\) is NOT the correct explanation of \(A\).
2 Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\).
3 \(A\) is not correct but \(R\) is correct.
