Question

he is plucking flower (change in passive voice)​

Answer 1

Answer:

flower is being plucked by him

Answer 2

Answer:

Flower is being plucked by him.

Explanation:

You should read the rules for transformation of active voice into passive voice. As there are so many rules, I can't write all of them.

The basic rule is, we change the verb to v3 while changing to passive. We use be before verb and verb is in its 3rd form, that is, we write be + v3

There are seven forms of be - is, am, are, was, were, been, being

The form of be is used according ro the tense.

In your question, the tense used is Present Continuous , therefore being is used.

The verb is plucking. The v3 of plucking is plucked.

Therefore, plucked is used after being .

The object of the active voice becomes subject of the passive voice. In question flower is object and so it is used as subject.

Hope this helps
