The correct answer is option 3 - Legislature. The National Purse refers to the financial resources of a country, including revenues and expenditures. The Legislature is the organ of government responsible for making laws and determining the budget and spending of a country. In many countries, the Legislature consists of elected representatives who are responsible for representing the interests of the people and making decisions on financial matters. They review and approve the annual budget presented by the Executive branch, which includes the allocation of funds for various government programs and initiatives. The Legislature acts as the custodian of the National Purse by ensuring that public funds are used appropriately and in accordance with the law.
