The correct answer is option 4 - (d) 1, 2 and 3. If the Annual Union Budget is not passed by the Lok Sabha, it has several implications.

Option 1 states that the President of India asks the Finance Minister to resign. This is not entirely accurate. The President does not have the authority to directly ask the Finance Minister to resign in this situation.

Option 2 states that the Prime Minister asks the Finance Minister to resign. This is a more accurate option because the Prime Minister, as the head of the government, has the authority to ask any minister to resign, including the Finance Minister.

Option 3 states that the Finance Minister modifies the budget and presents it again. This is also a valid option because if the budget is not passed, the Finance Minister can make modifications to address the concerns or objections raised and present it to the Lok Sabha again for approval.

Therefore, option 4, which includes all three options, is the correct answer as it covers the possible actions that can be taken if the Annual Union Budget is not passed by the Lok Sabha.
