Answer:
Hawk
Explanation:
Dichlorodiphenyltrichloroethan which is also known as DDT is a colorless, tasteless and almost odorless crystalline chemical compound. It was originally developed as an insecticide and it causes harm to wildlife animals.
When the chemical are sprayed or gets in contact with the soil it is the terrestrial organisms such as plants and primary consumers who gets affected the most due to direct contact with the chemical.
Animals such as hawks who are arboreal and tertiary consumers from the list of options don’t get affected directly from the source of the DDT contamination which makes them least affected.
