b. nominal because college majors cannot br ordered

c. interval because hours are equal distance apart and there is a true zero

d. ordinal because there is an order, but not equal distances between categories, e.g. 0-10000 isn't the same as 10000-30000.  One has a difference of 10000 and the second a difference of 20000

e. ordinal because 1-10 is an order but you don't know whether the difference between 1 and 2 is the same as that between 2 and 3.
