                                    Answer: C - Meyer Friedman identified two personality types in the 1950s based on how they respond to daily stressors, Type A and Type B. Meyer Friedman was a researcher who pioneered the development of two personality types, A and B, according to how well (or poorly) they respond to the multiple demands of everyday life. Dr. Friedman described Type A personalities as high achieving, multitaskers who are always very stressed and in a hurry. Type B personalities, on the other hand, are described as easy going, relaxed, and not always in a hurry.
