Hello friends, <br/><br/>Which of these sentences makes more sense?<br/><br/>1) "That's what he is."<br/><br/>or<br/><br/>2) "That's who he is."<br/><br/>Actually, I feel 1) is correct, if this is the case I will like to know why what is used here even when we referring to a man.<br/><br/>Thanks a lot.
