Solution

The correct option is C 1835 times
The proton is approximately 1835 times heavier than the neutron. In most cases, atoms have an equal number of protons and electrons. But as protons are heavier than electrons, the electron does not contribute to the mass of the atom.
Hence option A is correct.
