Select the most appropriate option to fill in the blank.

I am expected to follow all your instructions, _________?

aren't I

The most appropriate option to fill in the blank is aren't I.

The sentence "I am expected to follow all your instructions, _________?" is a statement followed by a question tag. The statement is positive, so the question tag should be negative. The only option that is negative is "aren't I."

The other options are not appropriate because they are not question tags. The option "isn't it" is a question tag that is used to confirm something that has already been said. The option "am I" is a statement, not a question tag. The option "is it" is a question tag that is used to ask for confirmation of a fact.
