Each of the students has completed their assignments.
Explanation:
Although "students" is plural, the subject "Each of the students" is considered singular. Hence, we use the singular verb “has”.
Grammatical Rule Used:
When a sentence starts with “Each of”, it is treated as a singular subject and must take a singular verb.
