How many national oil companies are operating in Brazil?

• A. 3
• B. 2
• C. 4
• D. 5

Answer: (C)

National oil companies are government-owned or government-controlled firms that actively operate in the oil and gas sector. In Brazil, the government maintains involvement in the industry through several state-backed entities, so the total number of national oil companies operating there is four. Petrobras is the most well-known, but three other state-backed entities also participate in exploration, production, refining, or related activities. The count reflects active government ownership across the sector, not private or foreign companies.
