The sentence which uses possessive personal pronouns correctly is sentence (d).<span>Did you eat the whole potato and its skin?
the rest of the sentences should've been written like this:
</span><span>Alicia thought that the blue jacket was hers.
</span><span>The dolphin bobbed its head up and down.
</span><span>Yours was the one with the blue tag, on the table.</span>
So Ed but I love you very much stop cheating and actually try from your math teacher .
