Answer 2

Because chemistry is the subject which tells us about behavior and properties of materials or matter around us.

By knowing behavior of matter we can encode it in proper ways to make it beneficial for us which can be called as physics. Chemistry tells us how we exist and what can be done to exist healthy which can be called biology. This way chemistry leads to biology and physics so it is the king.
