The correct Active/Passive form of the given sentence is:

☀ Our dog was run over, but is finally out of the woods.

Explanation for other options:

☀ Our dog had been run over, but is finally out of the woods. This option changes the verb tense to past perfect ("had been run over"), which suggests an action completed before a certain point in the past. The original sentence is in the simple past tense, so the correct form should be "Our dog was run over, but is finally out of the woods."

☀ My dog was run over, but It's finally out of the woods. This option changes "our dog" to "my dog," which alters the meaning of the sentence. The original sentence refers to "our dog," so the correct form should be "Our dog was run over, but is finally out of the woods."

☀ Our dog had ran over, but is finally out of the woods. This option uses the wrong verb form. The correct form should be "Our dog was run over," not "had ran over." The correct form is "Our dog was run over, but is finally out of the woods."
