Complex emotions like jealousy, embarrment, or love are BEST explained by____.?

C. The hle theory. Because we have higher brain functions and the right/ability to choose. We are the only creature that can affect our own emotional state as well as choose how we will react. If a lion steels the kill of another there is no jealousy or embarrment only stronger and weaker. Where a man who steals from another can realize it's wrong, rationalize why it isn't and a whole gambit of other possible feelings, moods and thoughts. So in hind sight I guess I am coming down closer to B. than A. I think if it was just physiological than other species might have developed it by now.
