C. 1974
D. 1985

Answer 1

Hint: DDT full form is Dichloro diphenyl trichloroethane. It is the first synthetic insecticide that was developed in the early 1940s where it is used to combat the insect borne diseases like malaria and typhus and other insect borne human diseases, it was used in both military and normal civil populations.

Complete answer:
By the year 1945, DDT was launched in the united states of America and by that time there was permission to use this in the field of agriculture and also in the household fields.
In the time span of the year like from 1940 to 1970 the Use of DDT was more and it was stated that 40,000 million tons of DDT were used in this span, which means 1.8 million ton used every year globally
When coming to the composition of the DDT it is mainly made up of xylene or petroleum.
Whereas by the year 1962, the opposition had started for the DDT and one article was published and it’s telling about the environmental correlations and hazards for the animals and crops for the continued use of DDT. And this publication mainly said that DDT has the potential to cause cancer and it is mainly dangerous for the wildlife and the birds that feed on the agricultural crops.

So by considering all the hazards caused by the DDT, the US banned it in the year 1972 and it was banned worldwide in the same year.

Note:
Though it was banned in the year 1972, India had produced it in the year 2009, because to control visceral leishmaniasis and insect born malaria disease, while the china ceased the production of DDT in the year 2007.
