The rest mass of the proton is given as 938 MeV. To convert this into kilograms, we can use the famous equation E=mc^2, where E is the energy equivalent of mass, m is the mass we want to find, and c is the speed of light. Rearranging the equation, we get m=E/c^2. Substituting the values, we get m=938 MeV/c^2. To convert this into kilograms, we need to multiply by a conversion factor of 1.60 x 10^-13, which relates one megaelectronvolt to its equivalent mass in kilograms, giving us m=938 x 1.60 x 10^-13 kg = 1.503 x 10^-10 kg, which is closest to option C.
