Concept:The Consolidated Revenue Fund is the main government account used to finance all government operations.
Explanation:Government earnings are first paid into a central account called the Consolidated Revenue Fund.
This fund receives revenue from sources such as allocations from the federation account, taxes, court fees, fines, and other government incomes.
From this fund, the government settles all day-to-day expenses, including administrative overheads, salaries, and operational costs.
Because it is used to pay for the general running of the government, it is the fund that services all operations of government.
The other options, such as the Consolidated Reserve Fund, Special Operational Fund, and General-Reserve Fund, are not meant for financing all government operations but for specific or reserve purposes.
Hence, the correct answer is the Consolidated Revenue Fund.
Answer:A. Consolidated Revenue Fund
