Correct option is A
Explanation of the Correct Answer: · "Criteria" is the correct plural form of "criterion."
· The sentence refers to seven (a plural quantity), so we need the plural form "criteria."
Why Are the Other Options Incorrect? · (b) "criterias" → Incorrect; "criteria" is already plural, so adding an "s" is wrong.
· (c) "criterions" → Incorrect; "criterion" is singular, and "criteria" is its correct plural form.
· (d) "criterion" → Incorrect; it is singular, but the sentence requires a plural noun.
Thus, the correct sentence is:
"The seven criteria for accreditation were presented in a seminar organised by the university."
