The essential appositive in the sentence "astronomer maia mitchell discovered a comet in 1847 and went on to become the first professional female astronomer in the united states," is Maia Mitchel. The last option is correct.
An appositive consists on a noun or noun phrase that renames another noun right beside it. The appositive can be a short or long combination of words.
In this particular case, the words Maia Mitchell which is a proper noun is renaming the noun astronomer, which is right before it and constitutes the subject of the sentence.
The key questions to ask when refining and polishing your thesis statement are: does the thesis question address the assignment? Can you clarify any vagueness in phrasing or assertions? Are there any alternatives to your thesis statement?
