This statement directly matches the definition of the law of conservation of matter, which states matter is neither created nor destroyed, only transformed in form. The other options describe unrelated scientific principles: the second law of thermodynamics relates to entropy, Dalton's laws focus on gas mixtures/atomic theory, and Charles's law concerns gas volume and temperature.
