Consider the following relation for published books:BOOK (Book_title, Authorname, Book_type, Listprice, Author_affil, Publisher)Author_affil refers to the affiliation of the author. Suppose the following dependencies exist:Book_title → Publisher, Book_typeBook_type → ListpriceAuthor_name → Author-affil (a) What normal form is the relation in? Explain your answer.(b) Apply normalization until you cannot decompose the relations further. State the reasons behind eachdecomposition.

(a) What are the significant functional dependencies in this relation? (b) What is/are the candidate key(s) of this relation? (c) is this relation in 1NF, 2NF, 3NF, BCNF? And why?
Q3: Define a relation prereq depth(course id, prereq id, depth) where the attribute depth indicates how many levels of intermediate prerequisites there are between the course and the prerequisite. Direct prerequisites have a depth of 0. Note that a prerequisite course may have multiple depths and thus may appear more than once.
