Option B
Electrons has a negative charge
<u>Explanation:</u>
Electrons are the negatively charged shreds of an atom. Collectively, the positive charge of the protons in the atomic nucleus are neutralized by each of the electrons of an atom engenders a negative charge. Electrons are notably meager associated with all of the distinct components of the atom.
