D.None of these.

Answer 1

Hint: Euro norms refers to the European emission standard which sets a particular limit for the emission of different fuels from vehicles.

Complete answer:
Euro 2 was given for cars and motorcycles
1)Euro 2 was first approved in January 1996 and the first registration was done in January 1997 for petrol and diesel emission of only light passenger cars.
2)Whereas for motorbikes, the first approval of Euro 2 norms was done in January 1997 and the first registration in October 1997 for petrol and diesel emissions.
3)Euro 2 was first approved in January 1998 and the first registration was done in October 1998 for petrol and diesel emission of light commercial vehicles which weighed below 1760 kg.
4)Euro 2 was first approved in January 1998 and the first registration was done in October 1999 for petrol and diesel emission of light commercial vehicles which weighed above 1760 kg.
5)According to the Euro 2 norms, the emission of sulfur must be controlled at 350 ppm in diesel and the emission of sulfur must be controlled at 150 ppm in petrol.
6)And according to the Euro 2 norms, the aromatic hydrocarbons are to be contained at 42% of the concerned fuel.

Option D: All the given options are correct as all the statements are true regarding Euro 2 norms. Therefore, this is the correct option.

All other options are irrelevant.

Hence, the correct answer is option (D)

Note: 1)The different stages of European emission standards are Euro 1, Euro 2, Euro 3, Euro 4, Euro 5, Euro 6. All these norms helped reduce the emission of harmful gases and fuel in the air.
2)Normally the diesel has more precise and strict regulations for the emission of carbon monoxide as compared to petrol.
