You are grading an Object-Oriented project submission. You find the following class:

Which of the following statements is correct?

PayrollManager inherits from Employee; it is responsible for Employee’s properties in addition to its own properties; and the variables should be declared as final.

PayrollManager has an Association with Employee; it violates Encapsulation because the local variables are not set as private; and 50.0 must not be used since the use of literals violates the DRY principle.

PayrollManager has a Dependency on Employee; it is perfectly architected because it successfully uses getters and setters to maintain Information Hiding.

100%

PayrollManager has an Association with Employee; it violates DRY because Employee’s methods are being called multiple times by PayrollManager; and 50.0 is a literal, which needs to be assigned to a named constant.

PayrollManager has a Dependency on Employee; it is responsible for Employee’s properties in addition to its own properties; and 50.0 is a literal, which needs to be assigned to a named constant.
