Answer:One is happy and the other is not
Explanation:
I think it is C.subject because he is pronoun, it can't be the object so A and D are wrong and B are also wrong because predicate nominative is a word in the nominative case that completes a copulative verb, so it didn't make any sense to me. In this case, the subject is in the back of the sentence "Danna and he".
It would be D. New information comes out all the time so when info is outdated, it isn't reliable at all. Hope this helps! :)
