Question

Which of the following is true regarding the physical sciences?
A) they deal with non-living things
B) The study of matter is conducted at atomic or ionic levels
C) Both a and b
D) None of these

Answer 1

Hint : Physical science is the study of inorganic matter which means non-living matter. There are various fields within the physical sciences.

Complete step by step answer
The physical sciences are a broad field of science that connects many disciplines together through its focus on the inorganic matter such as the Earth and its components, from rocks and soils to the ocean and atmosphere. The defining characteristic of the physical sciences is that it deals with physical systems that are composed of inorganic matter. This means that they deal with non-living objects. Hence option (A) is correct.
Physical sciences are a branch of natural science that tries to predict and explain various phenomena that happen in nature and in our universe. To understand how matter, what we are made up of, works, the study of matter must be done at an atomic or ionic level. This way we can know how atoms interact with each other, form connections in different ways, and make up different molecules. The study of matter at the ionic level consists of a separate branch in itself which is called chemistry while the phenomenon of how individual atoms work is studied in Physics. Hence option (B) is also correct.
Since both options (A) and (B) are correct, the right choice is option (C).

Note
There are various branches of physical sciences such as physics, astronomy, chemistry, and Earth sciences. In contrast to physical sciences, life sciences such as biology deal with organic and living objects and the way they function.
