Solution

The table violates 1NF because of both a and b. The "Author" column and the "Genre" column both contain multiple values in the same cell. According to the rules of the First Normal Form (1NF), each column in a table should contain only atomic (indivisible) values, and each cell in a table should contain only one value from the set of values that correspond to that column. Therefore, having multiple authors in the "Author" column and multiple genres in the "Genre" column violates these rules.
