The correct option is C charged
Let's examine the sentence: "Ajeya was _______ with a serious crime." The sentence needs a verb that is generally used for crime and the verb should also be used with the preposition "with" coming after the blank. So, Option A and Option B cannot be used here as "convicted" and "accused" are used with the preposition "of" and not "with." Similarly, Option C also cannot be used as "condemned" is not used with "crime" in legal language. So, Option D is the correct answer as "charged" is used for "crime" as well as with the preposition "with."
