Answer:
a. have determined.
Explanation:
The use of the verb "has" or "have" depends on the person and the number. Has is used for third-person singular whereas "have" is used for first-person and plural nouns or pronouns. And the main point to be used in this case is that "has" is for singular nouns whereas "have" is to be used for plural nouns.
Looking at the given sentence, <em>"A variety of researchers over the years has determined the evolutionary sequence . . ."</em> the noun "researchers" is plural. This determines the form of the verb to be used alongside it.
Thus, the acceptable revision of the verb will be "have determined".
