Hint: Try to recall that chloropicrin is one of the tear gas which is also called trichloronitromethane. It is a toxic and organic compound. Now, by using this you can easily find the correct option from the given ones.

Complete step by step solution:
It is known to you that there are different types of compounds that may be used as tear gas.
Tear gas is formally known as lachrymator agent or lachrymator (meaning “tear”).
When chloroform is heated strongly with concentrated nitric acid, then nitro chloroform is obtained. This is also called chloropicrin. The chemical formula of chloropicrin is\[CC{{l}_{3}}N{{O}_{2}}\].
The reaction for preparation of chloropicrin is as follows: \[CHC{{l}_{3}}+HN{{O}_{3}}\to CC{{l}_{3}}N{{O}_{2}}+{{H}_{2}}O\]
Chloropicrin also known as nitro chloroform is a chemical compound currently used as a broad-spectrum antimicrobial, fungicide, herbicide and insecticide.
It has the properties to irritate the mucosal membranes and causes draining of tears to remove the gas from eyes as soon as possible. It is also used as a tear war gas.
The vapours of chloropicrin are irritating to the skin, eyes and upper respiratory tract, and it has been used in chemical warfare.

Therefore, from above we can conclude that option B is the correct option.

Note: You should not forget that chloropicrin was used in world war as a chemical weapon and it was too dangerous for both animals and humans. It mainly affected the breathing mechanism.
It can also be prepared by the reaction of nitromethane with sodium hypochlorite.
