The worlds largest biofuel plant with an annual production capacity of about 110 million litres of fuel has been set up in which country?

Introduction / Context:
Biofuels have become an important alternative energy source as countries look for ways to reduce dependence on fossil fuels and lower greenhouse gas emissions. Some nations, especially those with large agricultural sectors, have invested heavily in massive biofuel production facilities. This question refers to a widely cited fact about the worlds largest biofuel plant, with a capacity of approximately 110 million litres per year, and asks in which country this plant has been established.

Given Data / Assumptions:

- The plant is described as the worlds largest biofuel plant. - Its production capacity is about 110 million litres of fuel annually. - The options given are China, India, Brazil and USA. - The question expects familiarity with standard environment and energy related GK facts.

Concept / Approach:
Brazil is one of the leading producers of biofuels, especially ethanol derived from sugarcane. It has a long standing national programme promoting bioethanol and uses high blends of ethanol in vehicle fuel. The specific landmark of setting up the worlds largest biofuel plant with an annual capacity of 110 million litres is commonly attributed to Brazil in exam oriented materials. Therefore, recognising Brazil as a biofuel superpower helps identify the correct option quickly.

Step-by-Step Solution:
1. Recall that the major biofuel producing countries include Brazil, USA, and some European nations, with Brazil standing out for sugarcane based ethanol. 2. Among the options, Brazil has the longest history of large scale ethanol programmes and flexible fuel vehicles. 3. Many general knowledge question banks explicitly mention that the worlds largest biofuel plant with 110 million litres capacity is located in Brazil. 4. China and India are important energy consumers but are not usually credited with this particular world record facility. 5. USA is a major producer of corn based ethanol but this specific capacity based claim in exam questions is assigned to Brazil. 6. Therefore, Brazil is the correct answer.

Verification / Alternative check:
Verification can be done by consulting multiple environment and energy GK sources which repeat this question and mark Brazil as correct. These sources highlight Brazil role as a global leader in bioethanol and note that some of the largest integrated biofuel plants in the world operate there. This repeated association confirms that the question is based on that standard fact and that Brazil must be selected over the other listed countries.

Why Other Options Are Wrong:
China is rapidly expanding renewable energy, especially solar and wind, but the specific fact about the largest biofuel plant with 110 million litres capacity is not associated with it in standard GK references. India has biofuel initiatives, including blending ethanol with petrol and promoting biodiesel, but again this particular world record is not credited to India. USA is a leading ethanol producer but the question in common exam material usually identifies Brazil, not USA, as the location of this largest plant. Hence these three options are included to test a candidates understanding of which country is most strongly linked with massive sugarcane based biofuel production.

Common Pitfalls:
Because both Brazil and USA are famous for ethanol production, candidates sometimes get confused and choose USA thinking of its advanced technology. Others may guess India out of national bias, even though the question clearly speaks about a world record facility. To avoid such mistakes, students should remember that Brazil is the classic example of a country where ethanol from sugarcane has been integrated into mainstream fuel use for decades and that it often appears as the correct answer in biofuel related general knowledge questions.

Final Answer:
The worlds largest biofuel plant with an annual capacity of about 110 million litres of fuel has been set up in Brazil.
