Answer:
The correct answer is C. Cells.
Cells are the basic building blocks of all living organisms. They are the smallest unit of life and are responsible for carrying out various functions necessary for the survival of an organism. Cells are made up of different types of tissue, which are groups of similar cells that work together to perform a specific function.
For example, in the human body, there are different types of tissue such as muscle tissue, nerve tissue, and connective tissue. Muscle tissue is responsible for movement, nerve tissue transmits signals throughout the body, and connective tissue provides support and structure.
Organs, on the other hand, are made up of different types of tissues. Organs are structures composed of multiple tissues that work together to perform a specific function. For instance, the heart is an organ made up of muscle tissue, connective tissue, and nerve tissue.
Atoms are the smallest unit of matter, and organelles are specialized structures within cells that perform specific functions. While both atoms and organelles are important in biological systems, they are not made up of different types of tissue.
In conclusion, cells are made up of different types of tissue, making them the correct answer to the question.
