B is the only right answer. A person is a "tow-head," not a "toe-head." Tow is a type of light-colored rope. If you're a tow-head, you have very light hair.

• A: You can't pour over things. You pore over them.
• C: You're not a shoe-in. You're a shoo-in.
• D: Lakes aren't teaming with anything. They teem.

Homophones are kind of a bitch sometimes. Better get used to it or you'll be pouring on important papers, throwing shoes at sure bets, and trying to join a team with a body of water full of something unpleasant.
