PART B: This is a true statement because opposite charges attract each other, whereas like charges repel each other. PART C: This is a true statement because the mass of a neutron is $1.67 x 10^{-27}$ kg, whereas the mass of an electron is $9.11 x 10^{-31}$ kg. PART D: This is a false statement because both the proton and the neutron have nearly the same mass.
