The correct answer is: Finance Minister.
The Finance Minister is the person who is responsible for the preparation and presentation of the annual budget of the government. The budget speech is a statement of the government’s financial policy for the coming year. It is delivered by the Finance Minister in the Parliament or the State Legislature.
The Chief Minister is the head of the government of a state in India. The Governor is the head of the state and is appointed by the President of India. The Speaker of the Assembly is the presiding officer of the Legislative Assembly of a state.
The Finance Minister is the most appropriate person to deliver the budget speech because he/she is the one who is responsible for the preparation of the budget. The Chief Minister and the Governor are not directly involved in the preparation of the budget. The Speaker of the Assembly is not involved in the preparation of the budget and is not the most appropriate person to deliver the budget speech.
