This is a duplicate of question 3689 with only minor spelling differences. Gerd Müller of West Germany scored two hat-tricks in the 1970 World Cup against Bulgaria and Peru. The correct answer is Gerd Muller (option C).
Gerd Müller scored two hat-tricks at the 1970 FIFA World Cup, part of a tournament-topping ten goals that cemented his reputation as one of the greatest goal-scorers in World Cup history. Franz Beckenbauer was a key West German teammate but was a defensive/midfield player, not known for hat-tricks, which rules him out.
