Solution

The correct option is C Lead
Leaded fuel in the form of lead gasoline is banned recently due to its extremely harmful effects on health and pollution caused by it. Combustion of leaded petrol leads to release of lead in the environment causing dangerous effects on the health of all living organisms and environmental pollution.
The main difference between leaded and unleaded petrol is the presence of an additive in leaded petrol called tetra ethyl lead.
So the correct option is C.
