Solution

The correct option is D $n e g a t i v e, p o s i t i v e$
On rubbing an ebonite rod with fur or cat's skin, the electrons from the fur gets transferred to the ebonite rod. The fur now has a deficiency of electrons and so is positively-charged. On the other hand, the ebonite rod has an excess of electrons and hence is negatively-charged. In the above example, the fur undergoes positive electrification. It should be noted that it is the electrons and not the protons that get transferred during positive (and negative) electrification.
Therefore, when an ebonite rod is robbed with fur. The charge on ebonite rod is negative and the charge on fur is positive.
