The correct option is C elements
The explanation for correct option:
(C) Elements
- Anything which occupies space i.e has volume and mass is called matter.
- According to modern research, the matter is made of basic building blocks, commonly called elements, which are 118 in number.
- An element is defined as a substance, which cannot be subdivided into two or more simpler substances by any chemical means.
- Therefore, the matter is made of basic building blocks, commonly called elements.
Explanation for correct option:
(A) Atoms
Atom is defined as the smallest unit of an element, which may or may not have an independent existence, but always takes part in a chemical reaction.It is defined as the smallest unit of an element
(B) Molecules
A molecule is defined as the smallest unit of matter, which has an independent existence and can retain the complete physical and chemical properties of matter. It is defined as the smallest unit of matter.
(D) Compounds
Compound: A pure substance that consists of two or more elements chemically combined in a fixed ratio is called a compound.it can be broken down into simpler substances by chemical methods.
Hence, the correct answer is an option (C).
