Objective pronouns can also function as:
A. the subject of a verb
This, however, is inaccurate since objective pronouns are not typically used as the subject of a verb; rather, they serve specific roles such as direct objects, indirect objects, or the objects of prepositions. The correct usage of objective pronouns is primarily in the context of receiving the action of the verb rather than performing it.
For the list you provided, none of them correctly describes an additional role of objective pronouns. If you have any confusion about usage, I'm here to clarify!
