A Correct answer
Explanation

The phrasal verb 'call in' means to summon or request someone to come, especially a professional or expert. When you need a plumber's services, you 'call in' a plumber. Other options don't fit: 'call for' means to require or demand, 'call upon' means to invite someone to speak, and 'call off/on' are not used for summoning professionals.
