Explanation:
The underlined traits in the ER chart speak to essential key since they remarkably recognize the quality
(a)
(I) The level of the given relationship is 2 i.e it is a parallel connection among Book and Publisher. It is a one to numerous relationship from distributer to book in light of the fact that a distributer can distribute any number of books however a book will have only one publisher,so the cardinality will be 1 to 1..* (one to many)
(b)
(i) The degree of the given relationship is 2 i.e it is a binary relationship between Author and Book. It is a many to many relationship from Book to Author a book can be written by one or more authors and an author can write more than one book, so the cardinality will be 1..* to 1..* (many to many)
(c)
(i) As mentioned in part (b), the degree of given relation is 2 and cardinality is many to many (1..* to 1..*)
(d)
(i) The degree of the given relationship is 1 i.e unary relationship. It is a many to many relationship because one book can belong to any sets and a set can have any number of books, so cardinality is 1..* to 1..* (many to many)

Answer:
Option b. ArrayList‹Integer› = new ArrayList‹Integer›(10) does not correctly declare an ArrayList.
<u>Explanation</u>:
ArrayList in Java dynamically stores elements in it. It also called as re- sizeable array as it expands in size when elements are added and decreases when an element is removed from it. This array list class also allows to use duplicate and null values.
The syntax for creating Array list is as follows
ArrayList<Type> obj = new ArrayList<Type>()
Type specifies the type of ArrayList like Integer, Character, Boolean etc, and obj is the object name. But in the option b ArrayList‹Integer› = new ArrayList‹Integer›(10) object name is missed and not specified.
