c) both glass rod and the cloth both acquire negative charge.
d)glass rod becomes negatively charged while the cloth has a positive charge.

Option (b)
The glass rod becomes positively charged, while the cloth will have a negative charge. Glass happens to lose electrons easily, and silk grabs them away from the glass atoms, so after rubbing the glass becomes positively charged and the silk becomes negatively charged.
