Turn the sentence below to passive voice:
her parents will meet jackie.

Explanation:

The passive voice highlights the importance of the object (thing or person) that receives the action of the verb while the active voice places in first term the subjcet that perfoms the action.

In the sentence Her parents will meet Jackie, the parents perform the action of meeting Jackie (in the future), so Her parents are the subject and Jackie is the object (she receives the action).

That means that in the passive voice, you must place fisrt Jackie, who is the object in the original sentence

The passive voice is made using the appropriate tense of verb to be plus the past participle of the action verb.

The past participle of meet is met.

You must keep the future tense, so the correct form of the verb to be is will be.

In conclusion, the correct way to turn the given sentence to passive voice is:
