A
electron
B
proton
C
neutron
D
atom
Explanation: 

Detailed explanation-1: -A proton is one of three main particles that make up the atom. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

Detailed explanation-2: -Protons are positively charged sub-atomic particles which are present in the nucleus of an atom. The charge on a proton is equal and opposite to the charge on an electron. The charge on the proton is. 6 × 10-19 C which is very very small.

Detailed explanation-3: -On the atomic level, protons are positively charged and electrons are negatively charged.
