How will you show that electrons are negatively charged particle ?

Electronic energy is negative because:

If an object made of substance A is rubbed with an object made of substance B, then A becomes positively charged and B becomes negatively charged. If however, an object made of substance C, then A becomes negatively charged, What will happen if an object made of substance B is rubbed against an object made of substance C? (a) B becomes positively charged and C becomes positively (b) B becomes positively charged and C becomes negatively charged. (c ) B becones negatively charged and C becomes positively charged. (d) B becomes negatively charged and C becomes negatively charged.
