The correct option is B Songs from my new album were being sung by me.
The correct answer is ‘Songs from my new album were being sung by me.’ This is because the subject pronoun ‘I’ in active voice changes to object pronoun ‘me’ in passive voice. And, the sentence in passive voice follows the structure of, receiver, ‘songs from my new album’ + the plural verb, ‘were’, as the noun ‘songs’ is plural + being, as the sentence in active voice is in the past continuous tense + past participle of the verb ‘sing’, which is ‘sung’ + by + the doer of the action, ‘me’.
