J. J. Thompson is credited with discovering the electron. Option B is correct.

Sir Joseph John Thomson was an English physicist and Nobel Laureate in Physics. In 1897, J. J. Thomson discovered the electron, (the first subatomic particle to be discovered), by experimenting with a Crookes, or cathode ray, tube. He proved that cathode rays were negatively charged. Moreover, he also studied positively charged particles in neon gas.

Thomson was awarded the 1906 Nobel Prize in Physics.
