The correct sentence which makes use of a PREDICATE NOMINATIVE is option "A": <em>It is </em><em>them and me in the picture.</em>
A predicate nominative may be a noun or a pronoun that completes the linking verb and renames the subject. We consider the following verbs as linking verbs: the verb to be in all its forms (am, is, are, was, were, be, being, and been) and the sense verbs (taste, smell, sound, look, feel...).
A is the only logical answer here. Plant 2 was the tallest starting off, but there's no other answers that include it that way. Hope this helps you out! :)
