Elle Woods has it all. She’s the president of her sorority, a Hawaiian Tropic girl, Miss June in her campus calendar, and, above all, a natural blonde. She dates the cutest fraternity boy on campus and wants nothing more than to be Mrs. Warner Huntington Ⅲ. But, there’s just one thing stopping Warner from popping the question: Elle is too blonde. Growing up across the street from Aaron Spelling might mean something in LA, but nothing to Warner’s East-Coast blue blood family.

"Elle Woods has it all" underlined Paragraph 1 means that ______.

A. She has everything to herself
B. She has all the advantages that any gift may dream of
C. She has ail the things she wants
