There are Liquid fuels like Biodiesel and there is real progress in Ethane as fuel also but it has not become commercial because they can be produced their own country without support from oil rich answer powerful countries.
As Indian mechanical Engineers you should take that responsibility to manufacture cars which can run on bio-diesel or solar energy cost-effectively.

The right answer is false, not all liquid fuel are produced from crude oil. Although majorly all liquid fuels are produced from crude oil there are several liquid oils out there that are produced from other sources, examples of these are hydrogen fuel, liquified natural gas, synthetic oil, and so on.

As in the all commercial vehicle, the main requirement is that we should obtain a large amount of energy from the small input of fuel and crude oil is the only way to extract this energy because it have low combustion nature and highly volatile that can produce large amount of energy.

There are some other fuels other than the derivatives of petroleum products such as methane(cal.value 55,530kj/kg).
Paraffin (46,000kj/kg).
Butane 49,510.
Ethanol 29,700 etc.
Can be used. Alcohol, 96% can be used as commercial fuel.

We are all know that petrol is coming crude oil by the process of petrol refining. In that process we get many commercial fluids like kerosene, diesel, grease etc. So we conclude that all commercial fluids are coming from crude oil.

Bio ethanol are alternatives for diesel and they produced from jatropha, Kanuga, cotton oil seeds etc. And they give nearly 13% less mechanical efficiency as compared to diesel.

Answer A is correct because of the basic is raw material and the raw material is crude oil and after that, we purifying at different temperature and get a different product.

In the case of commercial fuel: It is better to say that they all are not from mineral oils. For instance there is organic fuel oil that is made by using maize cereals.

All commercial fuels are derived from a natural source of oils.
All the commercial liquid fuels are derived from natural crude oil. Conventional source energy.

All commercial fuel are compounds of hydrocarbon hence they are derived from petroleum products as they contain different hydrocarbons.
