I can give you several sentences.It is my opinion that you could write this sentence yourself.She held a low opinion of him.What is your opinion of the painting?
This is a declarative sentence. It is stating a fact or opinion about someone.
In the sentence, "In your opinion the president was wrong about that." "that" is a pronoun. Its antecedent is presumably in a preceding sentence.

There is no sentence in the question on which to base an opinion.
An opinion is a personal view, essentially. An example sentence would be: His opinion was pretty offensive to everyone there.
