The study of matter and energy best describes physical science. Hence, option B is correct.
<h3>What is physical science?</h3>
Physical science is the study of the inorganic world.
Physics is a branch of science that studies matter and its motion through space and time, along with related concepts such as energy and force. Physics is one of the "fundamental sciences" because of the other natural sciences (like biology, geology etc.)
Thus the study of matter and energy best describes physical science. Hence, option B is correct.

The answer to the question is D
Answer:
In organic chemistry oxidation is the gain of oxygen atoms by any carbon atom or molecules.
Explanation:
Oxidation can be defined in multiple ways
1- Loss of electron
2- Increase in oxidation number
3- Loss of hydrogen
4- Gain of oxygen atoms
The last definition is the earlier one in organic chemistry.

Going down a group the acid strength increases because the bond strength decreases as a function of increasing size of the nonmetal, and this has a larger effect than the electronegativity.
<h3>What is Electronegativity? </h3>
A functional group or an atom's propensity to draw electrons to itself is referred to as its "electronegativity," which is a chemical attribute. An atom's atomic number and the separation between its valence electrons and charged nuclei have an impact on how electronegativity is determined.
For an atom to be able to draw electrons, it must be electronegativity. It varies in direct proportion to the gap between an atom's attraction to the electron and its potential for ionisation.
