The correct answer is B.

It is a scientific law.

A scientific law or physical is a theoretical principal that was defined using several facts. These may be a collection of experimental results or observations for long time. A scientific law is true under certain conditions.

 

So the attraction of objects to earth is a observation for long time. It is further experimentally defined by Newton in his law of universal gravitation.

Now this comment is true for certain conditions. The earth cannot attract everything. It will not attract sun or moon or other universe. So it has some limits.

 

Now it is clear that the above comment is scientific law.
