D Correct answer
Explanation

Tear gas contains chlorine-based compounds like CS gas (chlorobenzalmalononitrile) or CN gas (chloroacetophenone). The 'chlorine' in these compounds is what gives tear gas its irritating properties, causing tears and respiratory discomfort. Hydrogen, nitrogen dioxide (NO2), and sulfur are not the primary components of standard tear gas formulations.
