(1) These elements are excluded in the study of inorganic chemistry - hydrocarbons.

option A is the correct answer.

(2) It is a key component In the scientific method as this proves the whole experimentation process - hypothesis.

option C is the correct answer.

(3) A periodic table is an arrangement of the chemical elements on the basis of their atomic numbers, chemical properties and valence number.

option B is the correct answer.

What is inorganic chemistry?

Inorganic chemistry is concerned with the properties and behavior of inorganic compounds, which include metals, minerals, and organometallic compounds.

So hydrocarbons are excluded in the study of inorganic chemistry and included in the study of organic chemistry.

The key component in the scientific method is hypothesis, as this proves the whole experimentation process.

A hypothesis is a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.

A periodic table is an arrangement of the chemical elements on the basis of their atomic numbers, chemical properties and valence number.

Atoms or elements in the same group in the periodic table have equal valence electron.
