Step 1: Earlier, the Union Budget was presented on the last working day of February, and a separate Railway Budget was presented a few days before it. Step 2: From 2017, the Railway Budget was merged with the General (Union) Budget, ending a practice that had continued since 1924. Step 3: The presentation date was also advanced to 1 February so that the budget could be passed before the new financial year begins on 1 April. Step 4: The Budget is still presented by the Finance Minister in the Lok Sabha and still needs Parliament's approval, so the other options are wrong. Answer: The Railway Budget was merged with the Union Budget and the date was advanced to 1 February.
