Let us look at each of the answer choices.

I."¨ A small red bear may exist because nothing has been mentioned about the color of small bears.
"¨II. A small green bear"¨ may exist because nothing has been mentioned about the color of small bears.
III. A large green bear cannot exist because it has been mentioned in the question that all large bears are either red or blue, so there is n possibility that a large bear can be green in color.

The correct answer is A.
