The correct answer is C. Biology.
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it provides the chemical energy to drive the biological processes that support life.
Physics is the natural science that studies matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the scientific study of nature, encompassing a wide range of topics such as mechanics, electromagnetism, thermodynamics, quantum mechanics, and cosmology.
Chemistry is the science of matter at the atomic and molecular level. It is concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.
Mathematics is the science that deals with the logic of shape, quantity, and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, computers, software, architecture (ancient and modern), art, money, engineering, and even sports.
