Which statement about matter is correct?

• A. Matter is anything that has mass and takes up space
• B. Matter is only the stuff that is visible
• C. Matter is energy in disguise
• D. Matter is only found on Earth

Answer: (A)

The main idea here is how we define matter in science: matter is anything that has mass and takes up space. This means everyday substances like water, iron, air, and even tiny particles qualify as matter because they have mass and occupy volume. Energy is not matter, even though it can interact with matter and, via E=mc^2, is related to mass. Energy such as light or heat does not itself consist of matter and, in many cases, does not take up space in the way matter does (photons carry energy but have no rest mass). Matter isn’t limited to Earth either; it makes up the planets, stars, gas, dust, and living beings all across the universe. So this statement aligns with how scientists distinguish matter from energy and from non-Earth phenomena.
