<p>Technically, the last choice is correct.</p>
<p>“it is I” is a single verb phrase. “I” is the predicate nominative; it completes the verb and should therefore take the subjective (i.e., nominative) case: “I.” (“me” is in the objective case).</p>
<p>“whom” is the correct relative pronoun, as “it is I” is collectively serving as the direct object of “love.”</p>
<p>^ Neither of those topics is likely to appear on the SAT, though.</p>
<p>Going by ear isn’t consistent, but when you’re in a hurry, it works MOST of the time.</p>
<p>Unless, of course, your ear is grammar perfect</p>
<p>

<p>Maintaining an unerring ear for grammar is very difficult in the colloquial climate of high school. :)</p>
<p>Sad but true…</p>
<p>Silverturtle, are you in AP grammar or somethin…</p>
<p>
</p>
<p>No. My school does not even allow one to take the AP English classes until senior year. Moreover, the grammar education at my school is essentially nonexistent until senior year (nothing beyond parts of speech).</p>
<p>Silverturtle, will you be proud of me if I get an 800 W on Saturday ?</p>
<p>
</p>
<p>Ha ha. 
Well, obviously, it would be great if everyone whom I have tried to help did better than they otherwise would have. If this means that they get 800’s, that’s great; it shows that they have an acute sense of grammaticality and clarity in written communication.</p>
<p>hey silverturtle, are you taking the SAT this saturday?</p>
<p>^ Yes, I am.</p>
