Concept:The correct pronoun must match the function it performs in the sentence.
Explanation:"Me" is a first person singular object pronoun.
It is used when the speaker receives the action or is the object of a verb or preposition.
"I" is a subject pronoun, used when the speaker performs the action.
"Myself" is a reflexive or emphatic pronoun, used when the subject and object are the same person.
"Mine" is a possessive pronoun, used to show ownership without a following noun.
In an object position, only "me" is grammatically correct.
For example: "My friend invited me."
In a compound object, we still use "me": "My friend invited John and me."
We never use "I", "myself", or "mine" in such an object position.
Answer:A. me
