The correct answer is option 2: Contingency Fund of India. The Contingency Fund of India is a fund created by the government under Article 267 of the Constitution. It is used to meet unforeseen and urgent expenditure that cannot be planned or included in the budget. This fund is at the disposal of the President, and the government can access it without seeking the prior approval of the Parliament.

Option 1, Consolidated Fund of India, is incorrect because it is the fund into which all revenues received by the government are deposited, and its expenditure requires parliamentary approval. Option 3, Vote-on-Account, is also incorrect as it is a temporary provision for meeting the government`s expenditure before the full budget is passed. Option 4, From the Treasury, is vague and does not specify which fund it is referring to.

In conclusion, the Contingency Fund of India is the only fund from which unanticipated expenditure can be met without parliament approval.
