Answer: Option 'A'

Coupling is the degree of connection between pair of module

10.

Which of these is correct with context to coupling?

   A.) Failure to hide information leads to loose coupling and cannot be avoided
   B.) Modules that communicate using special data types and structures are less tightly coupled than modules with simple values

Answer: Option 'C'

When modules communicate only through public module interface, their coupling strength is proportional to the number of messages and number of data passed in between
