(a) and the cloth both acquire positive charge.

(b) becomes positively charged while the cloth has a negative charge.

(c) and the cloth both acquire negative charge.

(d) becomes negatively charged while the cloth has a positive charge

 

Answer

(b) becomes positively charged while the cloth has a negative charge.

 

When two objects are rubbed together, both get electrically charged but with different charges

By convention, the glass rod develops a positive charge.

The silk cloth develops an equal amount of opposite charge, and hence becomes negatively charged.
