We ................ by a loud noise during the night.

The correct choice is: "We were woken up by a loud noise during the night."

Explanation:

• "Woke": This is the past tense of "wake," but it does not fit well with the passive construction needed here.
• "Are woken up": This is the present passive voice, which is not appropriate for describing a past event.
• "Have woken up": This is the present perfect tense, used for actions that have relevance to the present, but it does not fit the context of a specific past event.
• "Were woken up": This is the past passive voice, which correctly describes an action that happened to the subject in the past.
• "Have been woking up": This is a grammatical error ("woking" should be "woken"), and the present perfect continuous tense is not appropriate for this context.

Therefore, "We were woken up by a loud noise during the night" is the correct choice, as it uses the past passive voice to indicate that the action of waking up was done to the subject by an external cause (the loud noise).
