**Matter and Its Components**

Matter is everything that occupies space and has mass. It includes everything we can see, touch, or feel, such as solids, liquids, and gases. Matter is made up of tiny particles called atoms and molecules. Atoms are the smallest unit of an element, while molecules are made up of two or more atoms bonded together.

**The Components of Matter**

Matter can be divided into two main components: atoms and molecules. Atoms are the building blocks of matter and cannot be broken down into smaller particles by ordinary chemical means. On the other hand, molecules are composed of two or more atoms that are chemically bonded together.

**Solids and Molecules**

Solids are one of the three main states of matter. They have a definite shape and volume. In solids, the molecules are tightly packed together and held in fixed positions by strong intermolecular forces. These forces keep the molecules close together, allowing solids to maintain their shape.

In a solid, the molecules vibrate around their fixed positions, but they do not move freely like in liquids or gases. The arrangement and motion of molecules in a solid determine its properties, such as density, hardness, and conductivity.

**Solutions and Molecules**

Solutions are homogeneous mixtures of two or more substances. They consist of a solvent (the substance that dissolves other substances) and solutes (the substances that are dissolved in the solvent). The solvent and solutes can be in different states of matter, such as solid solutes dissolved in a liquid solvent.

In a solution, the molecules of the solute are dispersed and evenly distributed throughout the solvent. The solute particles are surrounded by solvent molecules, forming a stable mixture. The interaction between the solvent and solute molecules determines the properties of the solution, such as its concentration and solubility.

**Molecules and Matter**

Since molecules are the building blocks of matter, they are present in all states of matter, including solids, liquids, and gases. Molecules determine the properties and behavior of matter. They are responsible for the physical and chemical properties of substances.

Therefore, molecules are the components of matter. They are the tiny particles that make up everything around us, from the solid objects we interact with to the solutions we use in our daily lives. Hence, the correct answer to the given question is option 'B': Matter.

Matter has 3 types : solids, liquids, gas. all of these have billions of molecules, which are made up of atoms. molecules are found in all sorts of matter, whether it is a book, the pacific ocean, or the oxygen that we breathe.
