The correct passive voice of the given sentence is Two good jobs have been found by Imran in the advertisements of the newspaper.

The active voice of the sentence is Imran has found two good jobs in the advertisements of the newspaper. This sentence is in the present perfect tense, which is used to describe an action that has happened in the past but is still relevant to the present. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "two good jobs" and the main verb is "find." The past participle of "find" is "found." So, the passive form of the sentence is Two good jobs have been found by Imran in the advertisements of the newspaper.

The other options are incorrect because:

• Two good jobs had found by Imran in the advertisements of the newspaper. is in the past perfect tense, which is used to describe an action that happened in the past before another action happened. There is no other action mentioned in the sentence, so the past perfect tense is not appropriate.
• Two good jobs are being found by Imran in the advertisements of the newspaper. is in the present continuous tense, which is used to describe an action that is happening now but is not finished. The sentence is describing an action that has already happened, so the present continuous tense is not appropriate.
• Two good jobs has found by Imran in the advertisements of the newspaper. is grammatically incorrect. The verb "to find" needs to be in the past participle form, which is "found."
