Why E not C

<ol>
<li>Psychologists advise that before making any major changes in your life, a person needs to focus on one's goals.</li>
</ol>

<p>(A) your life, a person needs to focus on one's goals
(B) their life, a person needs to focus on their goals
(C) their lives, focus on the goals
(D) one's life, you should focus on your goals
(E) their lives, people should focus on their goals</p>

<p>their is parallel in this and hence E is correct.</p>

<p>Choice E to avoid the switch in person. A switches from second (your) to third (person, one’s). B switches from third plural (their) to third singular (person). C switches from third (their) to second (you understood). D switches from third (one’s) to second (you). E is the only one that has consistent person for the pronouns.</p>

<p>No… C does not switch from third to second person…</p>
