Research suggests that which of the following faces would be rated as most attractive? a. a face in which the distinctive features of the face have been digitally enhanced. b. a face with an unusually small forehead and unusually large lips. c. a face with unusually small ears and unusually large eyes. d. a composite face of multiple faces that have been digitally blended to produce an "average" face.

(D) A composite face of multiple faces that have been digitally blended to produce an "average" face.

Explanation:

According to research, it seems that the type of face that people find attractive is a face that might seem average-looking. The cause of this may be because we tend to prefer faces that look like someone we see on the street, but at the same time more attractive than usual. Since the face is a composite of several average-looking people, it is possible that their best features, when combined into one person, becomes an attractive individual.
