Q.A Government Company, under the Companies Act, 2013, is one in which the Government holds not less than:

The legal definition of a Government Company under the Companies Act, 2013 fixes a specific minimum Government shareholding threshold — it does not require full Government ownership.

Under the Companies Act, 2013, a company qualifies as a "Government Company" if not less than 51% of its paid-up share capital is held by the Central Government, a State Government, or jointly by both (including together with any existing Government company). The Government need not hold 100% — a company remains a Government Company as long as the 51% threshold is met, even with private/other shareholders holding the remaining stake. Options (a), (b) and (d) do not match this statutory threshold.

Assuming a Government Company must be 100% Government-owned — the statutory test is a minimum of 51%, not full ownership.
