Question

I have a pen. (CHANGE VOICE)

Answer 1

heya mate

as there is no passive voice

reason

Non linking verbs cannot be used for constructing passive voice.  Hence,have is the one of them{non-linking verb}

but if in the sentence it will be ' I owned the pen ' it can be converted into passive as 'The pen is owned  by me '

remember

when forming a passive construction, the tense in the active sentence matches the tense of the auxiliary to be (is/was) in the passive sentence.
