B. Marta was given a note by the teacher to take home to her parents.

Explanation:

In active voice, the correct word order is subject (the one who does something) - verb (doing something; action) - object (the one who endures the action).

In passive sentences we change the place of the subject (the teacher) and the object (Marta), so the one who performed the action (the teacher) comes after the one who endured the action (Marta).

Predicate in passive sentences consists of different forms of the verb to be (was, is, am, are, have been, has, will be, being, and will have been) and past participle.

So, if the one who performs the action occurs or omits after the one who endured the action and if the form of the verb to be followed by a past participle, it is passive voice.
