Convert the given statement into passive voice. 

"We will conduct the operation next week".

In the active voice, the subject performs the action. The given statement "We will conduct the operation next week" is in active voice. Here, the subject is "We" who is doing the verb "conduct". In the passive voice, the subject will be shown as affected by the verb. We need to convert it into passive voice where the subject receives the action in the name of the verb. Option A is incorrect since it does not mention the subject "We". When the active voice uses "will" and the simple future of the verb, the passive voice will become "will be" and the past participle form of the verb. Option B is eliminated due to this. Option D does not even mention the subject. Option C follows all the rules and hence it is the right answer.
