An alcohol, XXX, reacts with sodium metal to produce gas YYY. When alcohol X X\,X is reacted with an oxidising agent, it forms carboxylic acid ZZZ. Carboxylic acid Z Z\,Z reacts with sodium carbonate to produce gas WWW.
Which row correctly identifies gas YYY, gas WWW, and the reaction type when X X\,X is converted to ZZZ?
Gas YYY: hydrogen; Gas WWW: carbon dioxide; Reaction type: oxidation
Gas YYY: carbon dioxide; Gas WWW: hydrogen; Reaction type: oxidation
Gas YYY: hydrogen; Gas WWW: carbon dioxide; Reaction type: reduction
Gas YYY: water vapour; Gas WWW: carbon dioxide; Reaction type: dehydration
