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

Detailed explanation-1: -Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons. “Free” neutrons are those no longer confined inside a nucleus. These free neutrons are produced by nuclear fission and fusion processes.

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: -A neutron is made of two down quarks and one up quark. One up quark has a charge of +2/3, and the two down quarks each have a charge of-1/3. The fact that these charges cancel out is why neutrons have a neutral (0) charge.
