An action in a sentence can be represented in two ways, namely active and passive voice.
The passive voice always uses the past participle form of the main verb irrespective of any tense. Only the auxiliary verbs depend upon the sentence given in active voice.
The correct answer is D) will be found as the previous sentence indicates future tense in the sentence after it.
Options A, B, and C are not correct as the sentence is not in the simple past tense, the future tense and helping verb is missing respectively.
