Answer:
a) We know that atleast one or more author writes a book.
Symbol to indicate one or more is (B)
So the correct option is B
b) We know that zero to multiple books are written by any author.
Symbol to indicate zero or more is (A)
So the correct option is A
c) The fourth option is correct if we replace by many to many relationship and generate a new entity.
So the relationship betweem author and contract is one to many. So we know that there is atleast one author that represent in symbol d and books has atleast 0 that represent in symbol c.
So Fourth Option is correct d at blue side and c at red side.
d) There are two forirgn keys in table Contract one is from AuthorId and other is ISBN.
So correcct option is C

Every hexadecimal digit represents 4 bits, so the address has 128/4 = 32 digits.
A GUID (Globally Unique IDentifier) has 128 bits. They are usually written like this:
{38a52be4-9352-4<span>53e-af97-5c3b448652f0}.</span>
There are different types of guids, depending on how they are generated. The first digit of the third group reveals the type. In the example above it is 4. A type 4 guid is fully random (except of course for the 4).
It is a method of work organization that seeks to increase productivity through the maximum division of functions, the specialization of work and the strict control of the time needed for each task.
