I believe you're talking of the Diet of Worms, which took place in the city of Worms in 1520 (option D).

Worms is a city in southwest Germany, today with 80 000 inhabitants.

The Holy Roman Emperor Charles V summoned Martin Luther to hear Luther’s claims as expressed in the Ninety Five Theses and the meeting took place in the city of Worms.  So for the given question, the correct option is option “D”. The Diet of Worms took place in the year 1527. It was an imperial diet of the Holy Roman Empire. Many imperial diets took place at the city of Worms, but the Edit of Worms was the most important among all the diets.
