Which of the following statements about red giant stars are true? (Select all that apply.) Red giant stars are less luminous than main sequence stars of the same temperature. Red giant stars tend to be more luminous than main sequence stars of the same temperatures because they are larger in size. Red giant stars are less luminous than main sequence stars because fusion happens more rapidly in main sequence stars. A red giant star of a given temperature is more...
