What are the names of the main characters in the Mysterious Benedict Society?

The main characters in "The Mysterious Benedict Society" are Reynie, Kate, Sticky, and Constance. This grouping represents the core team of young protagonists who come together to embark on a mission that requires intelligence and teamwork.

Reynie is the thoughtful and resourceful leader of the group, Kate is known for her physical agility and bravery, Sticky is the brainy one with an incredible knack for retaining information, and Constance is the smallest but plays a vital role with her unique perspectives and strong will.

The other options contain characters that are either not part of the main group or include names that do not match the actual characters from the book, which makes them inaccurate.
