(A) Borrowings from RBI -> Provides funds to finance the deficit.
(B) Disinvestment -> Generates revenue receipts by selling government stake in PSUs, helping manage the deficit.
(C) Increasing Subsidy -> This INCREASES revenue expenditure, thus WORSENING the revenue deficit rather than managing it.
(D) Borrowings from the general public -> Market borrowings provide funds to finance the deficit.
Hence, Option 2: (A), (B) and (D) only -> Revenue deficit occurs when revenue expenditure exceeds revenue receipts. It can be managed by: (A) Borrowings from RBI - creates funds to cover the gap; (B) Disinvestment - generates capital receipts that can be used to offset the deficit; (D) Borrowings from public - market borrowings provide financing. However, (C) Increasing Subsidy would increase revenue expenditure and worsen the deficit, so it cannot be a way to manage it. -> correct
