Hi regarding the sentences below:<br/><br/><i>You are the second person to say that I look younger than my age.</i><br/><br/><i>You are the second person who has said I look younger than my age.</i><br/><br/><i>You are the second person who said that I look younger than my age.</i><br/><br/>Could I get a confirmation that only the first 2 sentences are grammatically sound? Thanks,
