Your answer: —  Â·  Correct: B
Explanation

The creation of something from nothing (ex nihilo) is fundamentally against the law of conservation of mass-energy. This principle, derived from the First Law of Thermodynamics, states that in any system of constant mass, energy can neither be created nor destroyed, only transformed from one form to another [1]. Historically, the law of conservation of mass established that matter is not lost or gained during chemical reactions [2]. In modern physics, Einstein's mass-energy equivalence (E=mc²) unified these concepts, implying that the total quantity of mass-energy in an isolated system remains constant. Consequently, the appearance of matter or energy from 'nothing' would violate this balance. While some cosmological theories explore a 'zero-energy universe' to reconcile creation with these laws, the standard scientific framework maintains that mass-energy is conserved. Other options like constant or multiple proportions refer specifically to chemical composition ratios rather than the fundamental existence of matter [2].
