Question

It was _____ who swept the classA meB IC myselfD mine​

Answer 1

I think it’s A because that is the only one that sounds right

Answer 2

Answer:

B) I

(it was I who swept the class)

Explanation:

I happens before the verb "swept"

For example, mine does not work in this one because it can only be used after a noun; "This brush is mine."

myself can be flexible such as being used after pronoun or a verb.

"I did this myself." or "I myself will do this."

me is used after a verb. for example

"the one who swept the class was me."
