Select the most appropriate option that can substitute the highlighted word(s) in the given sentence.
"Manik said that it is mandatory that each student pay his/her tuition fees every month."

The correct replacement is (a) "each student pays."
Explanation:

· The sentence requires subject-verb agreement.
Other Options:

· (c) "Each students pay" – Incorrect, "each" takes a singular noun.
· (d) "Each student paids" – Incorrect, "paids" is grammatically incorrect.
Corrected Sentence:
· "Manik said that it is mandatory that each student pays his/her tuition fees every month."
Example Sentence:
