The correct passive form of the given sentence is The facts of the case had been presented well by the lawyer.

The active voice of the sentence is The lawyer had presented the facts of the case well. This sentence is in the past perfect tense, which is used to describe an action that had happened in the past before another action happened. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "the lawyer" and the main verb is "present." The past participle of "present" is "presented." So, the passive form of the sentence is The facts of the case had been presented well by the lawyer.

The other options are incorrect because:

• The facts of the case had presented the lawyer well. is in the active voice, while the question is asking for the passive voice.
• The facts of the case were being presented by the lawyer well. is in the present progressive tense, which is used to describe an action that is happening now. The action of presenting the facts of the case is not something that is happening now.
• The lawyer was presented well by the facts of the case. is in the passive voice, but the subject of the sentence is "the lawyer," which is not the one being acted upon. The subject of the sentence should be "the facts of the case."
