The correct answer is: B. Next to nothing of the events would be known to Jim.
The other options are incorrect because they do not use the passive voice correctly. In the passive voice, the subject of the sentence is acted upon by the verb. In this case, the subject is “Jim” and the verb is “would be known.” The correct way to write this sentence in the passive voice is “Next to nothing of the events would be known to Jim.”
Option A is incorrect because it uses the active voice. In the active voice, the subject of the sentence is the one doing the action. In this case, the subject is “Jim” and the verb is “was being known.” This sentence is not grammatically correct because it does not make sense to say that Jim was being known.
Option C is incorrect because it uses the wrong tense. The tense of the sentence should be the future tense, because the events have not happened yet. In this case, the correct tense is “would be known.”
Option D is incorrect because it uses the wrong pronoun. The pronoun “it” should not be used to refer to a person. In this case, the correct pronoun is “Jim.”
