Answer 1

$\huge\red{\tt{\underline {Required\:Answer:}}}$

My old books have been sold by me.

Explanation ↴

When changing the voice from active to passive, at first the subject, object, and verb of a sentence must be identified. Then, the tense of the verb must be noted, because to transform the voice from active to passive, the necessary form of 'be' verb should be used. It is succeeded by the past participle form of the main verb.

The given sentence is in present perfect tense and we know that the passive verb form in the present perfect tense is made by putting have/has + been before the past participle form of the verb.
