Answer 1

The correct answer is BS-VI.

Key Points

BS-VI stands for Bharat Stage VI, which is the latest emission norm implemented in India.
It was introduced to reduce the pollutants expelled from motor vehicles and came into effect on April 1, 2020.
BS-VI norms are equivalent to the Euro 6 standards which are followed in Europe.
The transition to BS-VI brought a significant reduction in emissions of nitrogen oxides (NOx) and particulate matter (PM).
Vehicles under BS-VI norms are required to use BS-VI fuel, which has lower sulfur content.
The implementation of BS-VI norms necessitated the use of advanced technologies like Selective Catalytic Reduction (SCR) and Diesel Particulate Filters (DPF) in diesel vehicles.

Additional Information

BS-IV
- BS-IV stands for Bharat Stage IV, which was the emission standard implemented in India before BS-VI.

- BS-IV norms aimed to control emissions from vehicles, but the limits were less stringent compared to BS-VI.
BS-V
- BS-V stands for Bharat Stage V, which was initially proposed as the next stage after BS-IV.
