Which of the following is covered in the Yoreh Deah book of the Tur?

The Yoreh Deah section of the Tur focuses on a wide array of laws related to various aspects of Jewish life, particularly those that pertain to the details of observance and ritual. This section encompasses laws on Kashrut (dietary laws), ritual purity, the treatment of certain animals, and other diverse topics, making it a repository of miscellaneous laws that do not fall into the more specified categories addressed in other sections.

While Shabbat and daily life are covered under the Orach Chayim section, and marriage and divorce are primarily discussed in the Even Ha'ezer section, finance and damages are addressed in Choshen Mishpat. Therefore, the unique aspect of Yoreh Deah is its broad collection of various miscellaneous laws that are essential to understanding the complex framework of Halacha, making it the appropriate answer to the question.
