Solution
The correct answer is a. "They cannot be assigned a value after declaration."
Here's why:
a. They cannot be assigned a value after declaration: This is true. In Java, a static final variable is a constant, which means once it has been assigned a value, it cannot be changed. The value must be assigned at the time of declaration or within the static block of the class.
b. They can be assigned a value at runtime: This is false. The value of a static final variable cannot be assigned at runtime. It must be assigned at the time of declaration or within the static block of the class.
c. They can be changed after being assigned a value: This is false. As mentioned earlier, a static final variable is a constant, which means once it has been assigned a value, it cannot be changed.
d. They can only be assigned a value in the static block: This is false. The value can be assigned at the time of declaration or within the static block of the class.
