Analyzing the question, In this question we have to determine that which of the four laws is a restatement of the conservation of mass. Mass energy equivalence:According the the Mass Energy equivalence, the mass and energy are interconvertible between each other. According to Einstein&#039;s theory, a mass m is equivalent to an energy of amount   E  =  m      c    2  , where c is the speed of light.As per energy conservation, energy can neither be created nor be destroyed.  Hence the amount of mass is also conserved in the universe.According to First law of thermodynamics, any dQ energy is given to an isolated system is equal to the sum of work done by the system dW and the change in internal energy dU. So   d  Q  =  d  U  +  d  WAccording to Charles law, the volume of an ideal gas directly proportional to the absolution temperature of the gas, at constant pressure.   V  ∝      T  According to Kirchhoff&#039;s law of radiation, ratio of the emissive power to the coefficient of absorption is constant for all the substances at a given temperature and is equal to the emissive power of black body.      E    a    =      E    b    =  constantAccording to Newton&#039;s second law, the force acting on a body is the rate of change of linear momentum of the body. The direction of acceleration of the body is along the net force acting on it. If mass of the body remains constant,   F  =  m  aHence among these four laws, the first law of thermodynamics is a proper restatement of conservation of energy, hence the mass-energy equivalence. Option A is the correct answer

The mass energy equivalence shows that conservation of mass is a restatement of A. the first law of thermodynamics. B. Charles' Law. C. Kirchoff's Law. D. Newton's Second Law.
