Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

The question "I – the 9th letter of the English alphabet" requires the selection of a linking verb that accurately represents the relationship between the subject "I" and the information provided about it. The subject "I" is a singular pronoun, and we need a verb that indicates a state of being or existence.

Option A) "is" is the present tense form of the verb "to be" and is appropriate here. It indicates that at this moment, the statement being made is true: "I" is indeed the 9th letter in the English alphabet.

Option B) "are" is incorrect because it is the plural form of the verb "to be," which does not match the singular subject "I."

Option C) "am" is also technically correct in terms of the format "I am," but it would not work in this specific context about being the 9th letter, as it does not directly link to the noun being discussed.

Option D) "will be" implies a future condition, which is inappropriate here, as the letter's position in the alphabet is a present factual statement.

Therefore, the clear and correct choice is A) "is," which effectively communicates the existing state of the subject "I."
