Answer: (C)

Verified step by step guidance

1. Understand the structure of an atom: An atom consists of a central region called the nucleus and an outer region called the electron cloud.
2. Identify the components of the nucleus: The nucleus contains protons and neutrons, which are tightly packed together at the center of the atom.
3. Recognize the location of electrons: Electrons are found in the electron cloud, which surrounds the nucleus and occupies most of the atom's volume.
4. Recall that the nucleus is the dense core of the atom where almost all the mass is concentrated, while the electron cloud is the space where electrons move.
5. Conclude that since the nucleus contains protons and neutrons and is located at the center, the correct answer to what is found at the center of every atom is the nucleus.
