e. All of the above

ANSWER: All of the above

Explanation:

The Supreme Court has imposed ban on use of five harmful heavy metals like lithium, antimony, mercury, arsenic and lead in the manufacturing of firecrackers as they cause air pollution.

The SC order came on a 2015 petition filed by three Delhi children who had requested the apex court to intervene to regulate the use of crackers and fireworks during festivals like Diwali.

The apex court held that it is the responsibility of the Petroleum and Explosives Safety Organisation (PESO) to ensure compliance of ban order particularly in Sivakasi in Tamil Nadu where there are large number of firecracker manufacturers.

It also asked CPCB (Central Pollution Control Board) and PESO to make collaborative efforts for setting up of standards with regard to air pollution caused by the bursting of fire-crackers.
