Answer»

The underlined part of the SENTENCE is GRAMMATICALLY incorrect.

The verb 'used’ should be used instead of the ADJECTIVE 'usable’. Also the appropriate preposition is 'as’ which is used to refer to the function that the caricatures have in this sentence.

Hence the correct answer is OPTION 4.
