Which two options compile when placed at line n1 in the main method?

Choose two

A director.stockOptions = 1_000;
B employee.salary = 50_000;
C manager.budget = 1_000_000;
D manager.stockOption = 500;
E employee.budget = 200_000;
F director.salary = 80_000;

Explanation

Each variable has the declared type Employee, so compile-time member access permits its public salary field only. Although director refers to a Director object at runtime, fields such as budget and stockOptions are not accessible through an Employee-typed reference without a cast.
