a)read
b)reads
c)reading
d)readed
The correct answer is “read.”
Explanation:
The verb “read” is irregular and is the same in both the present and past tense. In the present, when used with I, it remains “read” (pronounced as /red/ in the past tense, but as /riːd/ in the present).
The other options are incorrect:
“reads” is used with third-person singular subjects (he, she, it).
“reading” is the present participle form, used in continuous tenses (e.g., “I am reading”).
“readed” is not a correct form of the verb; “read” is used for both the present and past tense.
So the sentence should read:
I read a book.
