The question asks to match three phrasal verbs with their meanings. Let's analyze each one:

turn to sb for help directly expresses seeking assistance from someone.

turn up has multiple meanings including "appear" (The missing book turned up), "increase volume" (Turn up the music), or "discover" (Police turned up new evidence).

turn down means "refuse" (She turned down the job offer) or "reduce volume" (Turn down the TV).

Answer: B
