Anything that has mass and takes up space is called matter. Matter is the term used to describe anything that possesses mass and occupies space.
Matter is a term used in the field of physics and chemistry to describe anything that has mass and occupies space. It refers to all substances and materials that we encounter in our daily lives, including solids, liquids, and gases.
The concept of matter is based on the understanding that everything in the physical world consists of tiny particles called atoms or molecules. These particles are the building blocks of matter and are constantly in motion.
The mass of an object refers to the amount of matter it contains, which determines its inertia and gravitational attraction. The space occupied by an object refers to its volume, which can be measured or observed in terms of its dimensions or displacement of other substances.
Matter exists in various forms and states, ranging from the solid state (e.g., rock, metal) where particles are closely packed together, to the liquid state (e.g., water, oil) where particles are more loosely arranged and can flow, to the gaseous state (e.g., air, oxygen) where particles are widely spaced and move freely.
Understanding matter and its properties is fundamental to the study of chemistry, physics, and other scientific disciplines. By examining the behavior and interactions of different types of matter, scientists can gain insights into the structure of substances, the nature of chemical reactions, and the principles governing the physical world.
In summary, matter is the term used to describe anything that possesses mass and occupies space. It encompasses all substances and materials in different states and is the subject of study in various scientific fields.

B. Tambourines
C. Guitars
D. Voices
Answer:
Option (D)
Explanation:
From the remains of musical instruments that are collected by the archaeologists, scientists have predicted that the sound was first generated consciously, along with the creation of arts such as wall paintings, clay statuette during the time between 60,000 BC and 30,000 BC.
The human voice was usually considered to be the first musical instrument discovered by humans. In the initial period, people often used their hands to clap so that a clear rhythm can be obtained.
Archaeologists have collected early instruments such as whistles, pipes, and flutes that are made up of wood as well as from the bones of animals. Some of the old instruments include 'Tjurunga' and 'Harp'.
Thus, the human voice was considered to be the first instrument that prehistoric people probably have used.
hence, the correct answer is option (D).
