This particle has a neutral charge
A
electron
B
proton
C
neutron
D
atom
Explanation: 

Detailed explanation-1: -neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67492749804 × 10−27 kg-marginally greater than that of the proton but 1, 838.68 times greater than that of the electron.

Detailed explanation-2: -As you might have already guessed from its name, the neutron is neutral. In other words, it has no charge whatsoever and is therefore neither attracted to nor repelled from other objects. Neutrons are in every atom (with one exception), and they are bound together with other neutrons and protons in the atomic nucleus.

Detailed explanation-3: -The neutron is a neutral particle, which is stable only in the confines of the nucleus of the atom. Outside the nucleus the neutron decays with a mean lifetime of about 15 min. Its mass, like that of the proton, is equivalent to 1 amu (atomic mass unit).

Detailed explanation-4: -A proton has positive charge of 1, that is, equal but opposite to the charge of an electron. A neutron, like the name implies, is neutral with no net charge. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons).
