Select the correct objective case pronoun and its use in the following sentence: will you call katie and when you’re ready to leave?
i; indirect object
me; indirect object
i; direct object
me; direct object

My whole entire life I thought it was, for example : Timmy and I, but as I learned more about it and how English has been changing it is now : Timmy and me. Me is an indirect object because me isn't the main focus. Your answer is me; indirect object.

Will you call Katie and me when you’re ready to leave?

To check just remove Katie from the sentence.

Will you call I/me when you're ready to leave?

Me makes more sense then I.

Hoped I helped!

(Btw : You is the subject because that is what the subject should do)
