I dont think this might be correct but I think the answer is the 3rd one.
I believe this is a clause because it has a subject and a predicate
the predicate being: Inspirational leader
the subject being: Mohandas gandhi
sorry if im wrong i tried
here is the difference between a phrase and clause that i googled sice i didn't really know how to explain it
On the other extreme, the clause is a part of a sentence, that contains a subject (noun phrase) that actively performs an action (finite verb form). A phrase is a part of a clause or a sentence. As against, a clause is a sentence fragment. A clause has a subject and predicate, whereas a phrase doesn't.
I hope this helps x3
