 a. first the gravitational force separated from electroweak combined with strong; then electroweak and strong separated; then electroweak separated into weak and electromagnetic.
  b. first the electroweak force separated out; then gravitation separated out from strong; then electroweak separates into electromagnetic and weak.
  c. first the strong force separates; then electroweak separates out from gravitational; then electroweak separated into electromagnetic and weak.
  d. first electroweak force separated; then electroweak separated into electromagnetic and weak; then strong and gravitational separated.
  e. first gravitational force, electroweak, and strong forces separated into three; then electroweak separated into electromagnetic and weak.
