Solution

The correct option is A N-nitrosodimethylene
A carcinogen is any substance or radiation that promotes carcinogenesis, the formation of cancer. Carcinogens may increase the risk of cancer by altering cellular metabolism or damaging DNA directly in cells. N-nitrosodimethylene causes liver cancer, whereas some of the tobacco-specific nitrosamines cause lung cancer. Volatile N-nitrosamines induce tumours in a variety of human organs, including the tongue, oesophagus, lung, pancreas, liver, kidney and bladder.
So, the correct answer is 'N-nitrosodimethylene'.
