Answer 2

B. the glass rod becomes positively charged while the silk cloth has a negative charge.

Explanation:

When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge. The glass rod becomes positively charged while the silk cloth has a negative charge.

Option B is the answer
