Suppose you create a class square to be a subclass of geometricobject. analyze the following code:

class square extends geometricobject {
double length;

square(double length) {
geometricobject(length);
}
}
a. the program compiles fine, but you cannot create an instance of square because the constructor does not specify the length of the square.
b. the program has a compile error because you attempted to invoke the geometricobject class's constructor illegally.
c. the program compiles fine, but it has a runtime error because of invoking the square class's constructor illegally.
