Question

Neither Lanai nor I qualified for the final rounds. Determine the case and function of the underlined pronoun.

Answer 1

A.

Good luck.

Answer 2

I'll assume that the "I" is underlined.
The word "I" just references yourself and makes the reader know that you are talking about yourself and not some other person. As for case, it is Subjective; Lania is the complement of the subject, which is "I."
