Which statement about subatomic particle masses is true?

Explanation:
The masses of subatomic particles vary by a lot, with electrons being much lighter than nucleons. The electron’s rest mass is about 9.11 x 10^-31 kg, while a proton weighs about 1.67 x 10^-27 kg (roughly 1836 times heavier), and a neutron is about 1.0087 times the proton’s mass. This makes the statement that a proton is heavier than an electron clearly true and unambiguous. It’s also worth noting that the neutron is slightly heavier than the proton, but the simplest, most definite contrast here is proton versus electron. The masses are not identical, and electrons are not heavier than protons.
