Solution

The correct format to declare a union in C is:

b. union Employee{ int age; long salary;} employee;

Here's why:

  • In C, the keyword 'union' is used to declare a union.
  • 'Employee' is the name of the union.
  • The union contains two members, 'age' of type int and 'salary' of type long.
  • 'employee' is a variable of type 'Employee'. This is an instance of the union 'Employee'.

So, the correct format is 'union' followed by the union name, then the union members enclosed in curly braces, and finally the variable name.
