How are final variables different from constants in Java?

static
const
final
immutable

The correct answer is: const

The correct keyword to ensure a variable retains its initial value during runtime in Java is "const". Option A, "static", is used to create class variables rather than constant variables. Option C, "final", can be used to create a constant variable, but it allows the value to be changed at runtime using reflection. Option D, "immutable", is not a Java keyword and thus, is incorrect. Therefore, option B is the most suitable keyword for this purpose.
