With reference to Benzo(a)pyrene, consider the following statements: I...
Benzo[a]pyrene is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F).
The main source of atmospheric BaP is residential wood burning. It is also found in coal tar, in automobile exhaust fumes (especially from diesel engines). BaP is discharged in wastewater by industries such as smelters, particularly iron and steel mills and aluminum smelters, in all smoke resulting from the combustion of organic material (including cigarette smoke), and in charbroiled food or grilled meats. A 2001 National Cancer Institute study found levels of BaP to be significantly higher in foods that were cooked well-done on the barbecue, particularly steaks, chicken with skin, and hamburgers. BaP has been identified as a prime carcinogen in cigarette smoke
According to the National Ambient Air Quality Standards (NAAQS), there are twelve major pollutants including PM 10, PM 2.5, Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Carbon Monoxide (CO), Ozone (O3), Ammonia (NH3), Benzene (C6H6), Benzo (a) Pyrene (BaP), Arsenic (As), Nickel (Ni) and Lead (Pb). Hence the correct option is (d)

Explanation:
Benzo(a)pyrene:
Benzo(a)pyrene is a polycyclic aromatic hydrocarbon (PAH) that is a known carcinogen. It is formed during the incomplete combustion of organic matter.
Statements:
1. It is released due to the incomplete combustion of organic matter:
When organic matter such as coal, oil, gas, tobacco, and wood is burned incompletely, benzo(a)pyrene is released into the environment. This can happen during industrial processes or even in everyday activities like grilling food.
2. It is found in grilled and smoked meat and fish:
One of the common sources of exposure to benzo(a)pyrene is through the consumption of grilled or smoked meat and fish. When these foods are cooked at high temperatures, benzo(a)pyrene can form on their surfaces.
3. It is a monitored pollutant under the National Ambient Air Quality Standards:
Benzo(a)pyrene is considered a harmful air pollutant and is included in the list of monitored pollutants under the National Ambient Air Quality Standards. Monitoring its levels in the air is important for public health and environmental protection.
Conclusion:
All three statements are correct as benzo(a)pyrene is indeed released due to incomplete combustion of organic matter, found in grilled and smoked meat and fish, and monitored as a pollutant under the National Ambient Air Quality Standards.
